, and the orientation dependence of the plastic deformation behavior was examined at room temperature (RT). At 0?-orientation, temperature dependence of the yield stress was also examined... behavior more quantitatively, Fig.12 shows the variations in maximum stress, plastic strain and apparent yield stress as functions of the number of cycles. The maximum stress showed slight increase during......
Tensile and fracture behavior of DZ951 Ni-base superalloy CHU Zhao-kuang(储昭贶)1,2, YU Jin-jiang(于金江)1 , SUN Xiao-feng(孙晓峰)1, ZHAO Nai-ren(赵乃仁)1, GUAN Heng-rong(管恒荣)1, HU Zhuang-qi(胡壮麒)1 1... 2006 Abstract: The tensile and fracture behavior of DZ951 directionally solidified Ni-base superalloy was studied in the temperature range of 20-1 100 ℃. The fracture mode was examined by scanning......
