Trans. Nonferrous Met. Soc. China 23(2013) 2591-2597 Low cycle fatigue behavior of laser melting deposited TC18 titanium alloy Zhen LI, Xiang-jun TIAN, Hai-bo TANG, Hua-ming WANG Engineering Research... cycle fatigue (LCF) behavior of laser melting deposited (LMD) TC18 titanium alloy was studied at room temperature. Microstructure consisting of fine lamella-like primary α phase and transformed β......
cycle fatigue behaviors of the C11000 copper and H63 copper-zinc alloy were obtained by using a miniature tester that combined the functions of in situ tensile and fatigue testing. A piezoelectric... presents more obvious cyclic hardening behavior and more consumed irreversible plastic work during each stress cycle compared with C11000 copper for the same strain controlled cycling. Additionally, based......
DZ468合金高周疲劳性能研究刘恩泽1,郑志1,佟健1,宁礼奎1,管秀荣1(1.辽宁省沈阳市科学院金属研究所)摘 要:本文研究了新型镍基高温合金DZ468的高周疲劳性能.结果表明:当应力比R=-1时,在900和760℃条件下,DZ468合金的疲劳强度分别为290和300 MPa.DZ468合金的高周疲劳试样断口由疲劳源,疲劳区和瞬断区组成.裂纹在表面,次表面和内部缺陷部位萌生,裂纹扩展具有第Ⅰ和第Ⅱ阶段,随应力幅增加裂纹扩展速率增大.光滑试样的疲劳裂纹扩展方式与变形机制间存在一定的关系,位错的平面滑移,交滑移和......
