Derived from Russian alloy CHS88U, six experimental Ni-base alloys named as A to F in the Ni-Cr-Co-W-Ti-Al-Hf system are designed, evaluated and processed. One of these alloys, F, shows excellent high temperature tensile strength and ductility with superior creep rupture properties. As predicted by using modeling tools such as PHACOM and NEW PHACOMP, there is hardly the tendency for formation of topologically close-packed phase (TCP) phase in alloy F. Furthermore, through microstructural observation, it is also found that no TCP phase is formed in alloy F after long-time exposure at high temperature. So alloy F has well balance of phase stability and mechanical properties in view of application for gas turbines. It is proved that d-electron approach can be applied for design and development of nickel-base superalloys for gas turbine application. 相似文献

利用文献中一些计算公式对GH220合金中γ′相wt%、Vol%、化学组成式、合金错配度、γ及γ′的密度和合金的密度进行了计算,计算值与实验值吻合得很好,表明这些公式在GH220合金中的适用性。还计算了不同W、Mo、Al、Ti、V含量的GH220合金的Chemical composition of gamma prime phase of alloy,the density of gamma,gamma prime and of alloy have been calculated with some formulae in references. The results of calculation agree with the measured results. span style=\ r′相;错配度;分配比;密度;相计算 γ’-phase;mismatch;participation ratio;density;PHACOMP 1986 2021-11-15 S1 8 10.13374/j.issn1001-053x.1986.s1.006 叶锐曾,孙金贵,葛占英,高良. 某些计算公式在GH220合金中的应用[J]. 工程科学学报,1986,8(S1): 45-50.
