Micromechanical model for competition between intergranular and intragranular fracture in 7××× aluminum alloys ZHANG Xin-ming(张新明), LIU Wen-hui(刘文辉), TANG Jian-guo(唐建国), LIU Sheng-dan(刘胜胆) School... with precipitate free zones (PFZ) nearby the grain boundary, have received a great deal of attention due to their high strength, light mass, and yet poor fracture toughness. Experimental investigation......

fracture morphologies of L-PBF-fabricated parts: 4 Conclusions The phase transformation, melt pool evolution, texture evolution, microstructure features and nano-hardness of L-PBF-printed Ti-13Nb-13Zr/Ta.... The recrystallization texture is strengthened while the fiber texture is weakened when the tantalum content is increased. Due to the formation of refined martensite α′ grains during L-PBF, the compressive......
