Effect of annealing temperature on microstructure and mechanical properties of ultrafine grained brass produced by equal channel angular pressing / Suryadi, Andi Pramana Kusuma, Amin Suhadi, Dedi Priadi, Eddy S. Siradj
" The present study investigated the mechanical properties and microstructure of ultrafine grained (UFG) brass processed by four passes of equal channel angular pressing (ECAP) and annealed at elevated temperatures. The mechanical properties of all samples were assessed using tensile and micro-hardness tests. Microstructure analysis was performed using optical microscopy (OM) and scanning electron microscopy (SEM). Ultimate tensile strengths (UTS) and yield strengths (YS) of 878 and 804 MPa, respectively, ductility of 15%, and hardness of 248 HV were obtained for samples processed by ... "
