and adherent oxidation scale is presented in it. No crack is found, which indicates a better thermal shock resistance than composite H20S. Figures 5(a) and (b) show the typical cross section...J. Cent. South Univ. (2012) 19: 887-891 DOI: 10.1007/s11771-012-1088-0 Fabrication and plasma arc thermal shock resistance of HfB2-based ultra high temperature ceramics WENG Ling(翁凌)1, HAN Wen-bo(韩文波......
of thermal shock cycle index in this paper, results are listed in Table 1. As shown in Table 1, thermal shock resistance of undoping 10NiO-NiFe2O4 ceramics is the best, and the samples crack after 7 cycles. But thermal shock resistance of CaO doped 10NiO-NiFe2O4 composite ceramics becomes bad due to the increase of content of CaO. When CaO content is 0.5%, samples crack after four or five thermal......

for disaster resistance, especially the investigation of fatigue properties. Based on the shear-lag model, an usual composite model under cyclic loading is established. According to the Paris formula... fatigue crack are analyzed. And the Poisson ratio is considered also. Key words:interfacial debonding; fiber; matrix; cyclic loading; crack growth; [全文内容正在添加中] ......
Trans. Nonferrous Met. Soc. China 31(2021) 1023-1030 Thermal fatigue crack growth behavior of ZCuAl10Fe3Mn2 alloy strengthened by laser shock processing Guang-lei LIU1,2, Yu-hao CAO1, Kun YANG1, Wei..., and thermal fatigue properties of a ZCuAl10Fe3Mn2 alloy was investigated to improve the thermal fatigue performance and decrease the surface crack of high-temperature components. The microstructure and crack......
Microstructures and properties of aluminum film and its effect on corrosion resistance of AZ31B substrate ZHANG Jin(张 津)1, 2, YANG Dong-hua(杨栋华)2, OU Xin-bing(欧信兵)2 (1. School of Materials.... And the corrosion potential with aluminum film positively shifts. Thus aluminum film can increase the corrosion resistance of Mg alloys obviously. Key words: AZ31B magnesium alloy; aluminum films......
because the resistance of colony interfaces to crack growth is reduced as a result of the increase of the size of α platelets and colonies. Key words: TC4; hot isostatic processing; fatigue... 文献标志码:A Influences of hot isostatic pressing on fatigue crack propagation of TC4 titanium alloy thin wall casting FENG Xin1, PENG shuang1, MA Ying-jie1, LEI Jia-feng1, WU......
