"This book addresses the need for basic information on aluminum alloys and their tempers. The author provides the reader with an understanding of the advantages and limitations of aluminum alloy and temper combinations in terms of the relationship of their composition, process history, and microstructure to service requirements. The temper designation of an aluminum alloy provides the user with background information as to how the alloy has been produced in order to obtain specific and desired properties and characteristics. Since aluminum alloys offer an excellent combination of light weight, high-strength, great corrosion resistance, and reasonable cost, they have become one of the most commonly used metal groups today.

"Adanya perkembangan teknologi bahan, khususnya untuk aplikasi kabel penghantar listrik menyebabkan terjadinya pergeseran terhadap bahan yang digunakan untuk konduktor listrik yang sebelumnya menggunakan tembaga dan sekarang mulai digeser oleh paduan Aluminium. Pergeseran tersebut disebabkan oleh paduan aluminium mempunyai keunggulan dibandingkan dengan kawat tembaga antara lain; mempunyai berat jenis lebih rendah, proses pembuatan relatif lebih mudah, serta harga relatif lebih murah. Bahan konduktor tidak selalu berada pada lingkungan yang ideal. Isu pencemaran udara tidak luput dari kualitas bahan konduktor di lapangan, salah satu contohnya adalah hujan asam. Hujan asam dapat mempengaruhi kualitas bahan konduktor. Hujan asam dapat membuat korosi dan menurunkan konduktivitas. Penelitian ini bertujuan untuk mendapatkan penyebab menurunnya konduktivitas bahan konduktor aluminium dan paduan aluminium dengan melakukan pengujian konduktor yang terkontaminasi oleh larutan H2SO4. Bahan konduktor yang digunakan adalah aluminium murni, AlZrCe+Mg 1%+ Al2O31% dan AlZrCe + Al2O31%. Penelitian dilakukan dengan merendam bahan konduktor didalam larutan H2SO4 1%, 3%, dan 5% selama 7 hari dan data diambil pada hari pertama, kedua, ketiga dan ketujuh. Konduktivitas hari pertama dan ketujuh mengalami penurunan konduktivitas akibat larutnya butir butir aluminium dan paduan aluminium. kondisi awal konduktivitas aluminium murni IACS pada hari ketujuh atau 7x24 jam terjadi penurunan menjadi 57,584% IACS pada larutan 1%, 56,486% IACS pada larutan 3% dan 55,632% IACS pada larutan 5%. Hal ini dapat terjadi karena elektron bebas yang melewati kisi-kisi kristal yang terdistorsi, maka elektron-elektron akan dibelokkan sehingga jarak bebas rata-ratanya menurun atau tahanan listrik menjadi naik dan kisi kristal terdistorsi didapat dari paduan Aluminium

The development of materials technology, especially for the application of electrically conductive wires causing a shift to materials used for electrical conductors previously using copper and are now starting to be shifted by Aluminum alloy. The shift is caused by aluminum alloys have advantages over copper wire, among others; lower specific gravity, easy manufacturing process, cheaper price. Conductor materials are not always at the ideal environment.

The issue of air pollution does not escape from the conductor material quality in the field, one example is acid rain. Acid rain can affect the quality of the conductor material. Acid rain can create corrosion and lowers conductivity. This study aimed to obtain the decrease in the conductivity of the conductor material of aluminum and aluminum alloy conductors by testing contaminated by H2SO4solution Conductor material used is pure aluminum, AlZrCe Mg + 1% + Al2O31% and AlZrCe + Al2O3 1%.

The study was conducted by immersing the conductor material in solution H2SO4 1%, 3%, and 5% for 7 days and the data taken on the first, second, third and seventh. The first day of the seventh conductivity and conductivity decreased due to the dissolution of the items to aluminum and aluminum alloys. Initial conditions IACS conductivity of pure aluminum on the seventh day or 7x24 hours decreased 57.584% IACS into a solution of 1%, 56.486% IACS in a solution of 3% and 55.632% IACS at a 5% solution. This may occur because the free electrons which pass through a crystal lattice that is distorted, then the electrons will be deflected so that the mean free path decreases or the electrical resistivity to be increased and distorted crystal lattice obtained from Aluminum alloy."

"Because lithium is the least dense elemental metal, materials scientists and engineers have been working for decades to develop a commercially viable aluminum-lithium (Al-Li) alloy that would be even lighter and stiffer than other aluminum alloys. The first two generations of Al-Li alloys tended to suffer from several problems, including poor ductility and fracture toughness; unreliable properties, fatigue and fracture resistance; and unreliable corrosion resistance.Now, new third generation Al-Li alloys with significantly reduced lithium content and other improvements are promising a revival for Al-Li applications in modern aircraft and aerospace vehicles. Over the last few years, these newer Al-Li alloys have attracted increasing global interest for widespread applications in the aerospace industry largely because of soaring fuel costs and the development of a new generation of civil and military aircraft. This contributed book, featuring many of the top researchers in the field, is the first up-to-date international reference for Al-Li material research, alloy development, structural design and aerospace systems engineering."

"The book is intended to be a handbook, a general reference, and a textbook. It contains the background educational materials on parametric analyses, extensive data, and previously unpublished master high-temperature curves for wrought and cast aluminum alloys.ASM International has previously published extensive numeric factual data on the high-temperature tensile and creep properties of aluminum alloys in the book Properties of Aluminum Alloys: Tensile, Creep, and Fatigue Data at High and Low Temperatures. In addition to interest in the properties themselves, there is a great amount of interest in how these properties are analyzed to provide estimates of long-time service performance. The latter analysis makes use of parametric time-temperature relationships based upon rate-process theory, enabling the user to combine all time-temperature exposure curves into one master curve useful for extrapolation as well as interpolation. The purpose of this book to explain and illustrate such analytical tools, and to provide a broad range of illustrative examples based upon data from the previous publication, plus much previously unpublished data from Alcoa Laboratories.The theory of and procedures for the development of master parametric relationships for high-temperature creep and stress rupture data for aluminum alloys are based upon rate-process theory. The advantages and limitations of several such analyses will be discussed. Previously unpublished master curves will be provided for a number of aluminum alloys, including wrought alloys 1100, 2024, 3003, 3004, 5050, 5052, 5154, 5454, 5456, 5083,and 6061, plus several castings alloys, including 224.0, 249.0, C355.0, and 357.0."

The use of silicon aluminum alloys is often used in industrial fields, especially the automotive industry. Silicon aluminum alloys have good wear and corrosion resistance. However, it is necessary to increase the corrosion resistance properties of the alloy again. This study tested aluminum-silicon alloys under conditions of heat treatment and did not undergo heat treatment. The heat treatment carried out by Al-Si solution heat treatment with a temperature of 510°C and artificial aging at a temperature of 171°C. Tests carried out are X-ray Floresecence, X-ray Diffraction, Electrochemical Test Linear Sweep Voltammetry (LSV) and Cyclic Voltammetry (CV) methods. With heat treatment applied without artificial aging, it has the highest corrosion rate with a value of 0,176 mm/year in a solution of 3,5 wt% NaCl and 0,258 mm/year in a solution of 10,5wt% NaCl. The artificial aging process has a low corrosion rate with a value of 0,074 mm/year in a solution of 3,5 wt% NaCl on sample with 10 hours of aging and 0,154 mm/year in a solution of 10,5 wt% NaCl on sample with 5 hours of aging. The results show that heat treatment has an impact on shifting the peak angle and increases good corrosion resistance."

"The 7075 aluminum alloy (a typical Al–Zn–Mg–Cu alloy) is one of the most important engineering alloys. It is mainly used in the automotive industry, in transport and aeronautics, due to its excellent strength/weight ratio. The purpose of the present research is to model the behavior of 7075 aluminum alloy and to build an experimental database to identify the model parameters. Firstly, the paper presents an experimental device of simple tensile tests and the studied material on 7075 aluminum alloy. Thus, uniaxial tensile tests are carried out in three loading directions relative to the rolling direction. From experimental hardening curves and Lankford coefficients, the mechanical properties are extracted, particularly the various fractures owing to pronounced anisotropy relating to the material. Secondly, plastic anisotropy is then modeled using the identification strategy which depends on yield criteria, hardening and evolution laws. By smoothing experimental hardening curves in the tensile tests, a selection is made in order to choose the most appropriate hardening law for the identification of the studied material. Finally, a comparison with experimental data shows that the behavior model can successfully describe the anisotropy of the Lankford coefficient."
