Investigation on microstructure and internal friction for low density TiB2/ZL114 composites Haihong ZHAN1,Lingyan XU1,Zhengbing XU1,Jianmin ZENG1,Wenmao HUANG1 (1.Key Laboratory of Nonferrous... of K2TiF4 and KBF4 (LSM method). The composites were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The internal friction measurements were performed on DTM-Ⅱ-J dynamic......
Complete Maps for the Internal Oxidation of Ideal Ternary Alloys Forming Insoluble Oxides under High Oxidant Pressures () 摘要:This paper presents an analysis of the conditions of stability of the different forms of internal oxidation of ideal ternary A-B-C alloys, where A is the most noble and C the most reactive component, forming insoluble oxide and exposed to high pressures of a single......
RESEARCH ON THE FORMATION MECHANISM OF INTERNAL CRACK IN THE CONTINUOUS CASTING SLAB S.Y. Chen1,X.D. Yue1,G.W. Chang1,G.C. Jin1 (1.Department of Materials & Chemical Engineering, Liaoning Institute... dendrites. The initial crack formed during the middle and final stage of solidification may extend to the surface of the casting slab and become an internal crack. The results of the theoretical analysis......
J. Cent. South Univ. (2018) 25: 831-842 DOI: https://doi.org/10.1007/s11771-018-3787-7 Theoretical and experimental investigation on internal gear pair with small sliding ratio PENG Shuai(彭帅)1, MA... 2018 Abstract: Aiming at the issue of sliding ratio, an internal gear pair is proposed which consists of an involute internal gear and a pinion with quadratic curve teeth. Particularly, the contact......
appearances fatigued at around 106 cycles showed internal fractures originating from the flat facets of austenite grains for both alloys. The difference in fatigue strength at 107 cycles between...:The fatigue properties of nickel-base Alloy 718 with fine- and grain-coarse grains were investigated. In the fine-grain alloy, the fatigue strength normalized by the tensile strengtn was 0.51 at 107 cycles......
Article ID: 1003-6326(2005)02-0414-05 Influences of post-annealing and internal stress on magnetoresistance properties of Ni80Fe20 films GAO Yan-qing(高艳清), WU Ping(吴 平), CAI En-jing(蔡恩静... 450℃. The internal stress in the films deposited on K9 glass is compressive and the resistance measurement shows that RM∥ is larger than RM⊥ in these films. However, in the films deposited at the same......
