Weibull Probability Model for Fracture Strength of Aluminium (1101)-Alumina Particle Reinforced Metal Matrix CompositeA. Suresh Babu,V. Jayabalan摘 要:In recent times, conventional materials are replaced by metal matrix composites (MMCs) due to their high specific strength and modulus. Strength reliability, one of the key factors restricting wider use......

of Ti is more dominant. Key words: Ti-6Al-4V alloy; NiTi intermetallic; laser metal deposition; corrosion behaviour 1 Introduction Ti-6Al-4V alloy is considered a capable structural material... powders were used to form in situ NiTi intermetallic-thin surface coatings on the Ti-6Al-4V substrate. The laser metal deposition technique was employed to melt powders of different compositions: Ti50Ni50......
文章编号:1004-0609(2010)S1-s0624-03 Ti-6Al-4V合金棒材α层厚度的测定 邵 军,朱玉香 (宝鸡钛业股份有限公司,宝鸡 721014) 摘 要:钛材表面形成的氧化层是由钛的氧化物(TiO2)和α层两部分组成的.讨论了用金相法测定TC4合金棒材的α层厚度时,加热温度,加热时间与α层厚度的关系,采用扩散方程对该试验数据进行了校对验算.从而得出:在成品生产工序中,TC4合金棒材的α层厚度一般不超过0.15 mm. 关键词:金相法;α层厚度;Ti-6Al-4V合金 中图分类号:TG 146.2 文献标志码:A Determination of α-layer thickness for Ti-6Al-4V alloy bar SHAO Jun, ZHU Yu......
compaction and integrity were produced by deposition of two separate layers under identical coating conditions. Key words: metal matrix composite; Ni-Al2O3 graded coating; structural characterization 1 Introduction Metal matrix composite (MMC) coatings reinforced with ceramic particles have received significant attention due to their relatively low cost and easy production by electro co-deposition......
