A review of composition evolution in Ni-based single crystal superalloysWanshun Xia1,Xinbao Zhao1,Liang Yue1,Ze Zhang21. Institute of Superalloys Science and Technology, School of Materials Science... crystal superalloys(Ni-SXs) are extensively applied in modern aero-engine and industrial gas turbine. Apart from the special single crystal structure which is disadvantageous to extension of creep......

Study on the Hydrate Activity of Fine Building Waste邢伟宏摘 要:<正>This paper discusses the way to activate building waste in order to increase the amount of waste used in building material products. Different admixtures are studied. The results show that the strength of hardened cement mortar with admixtures is higher than that without admixtures......
to the result. Key words: L12 type intermetallic compound; phase equilibrium; Co-Ti-Ta; Co-based superalloys 1 Introduction The development of superalloys has been driven by the demand to increase... Co-based and Ni-based superalloys, and it has been known that Ta can stabilize the γ′ phase [1-5]. However, both γ′-Ni3Ta and γ′-Co3Ta are not stable, thus, a quantitative thermodynamic description......
