摘要
两相铬镍合金65Cr-(31-35)Ni - ti - v - w的强化机理与热处理方式有关:α-相(合金基体为Ni在Cr中的固溶体)在硬化和平衡状态下的晶格周期基本相同;合金的强度和延展性决定了热处理时γ-软核(Cr固溶于Ni中)的弥散和释放量，其硬度小于α-相。1250°C单相淬火，800 ~ 900°C回火，强度高于退火合金，高温失效起始温度升高。破坏的性质取决于温度。在等黏温度以下，γ相的影响更为明显。
On the mechanism of chromium-nickel two-phase alloy strengthening and fracture
The mechanism of strengthening of a two-phase chromium-nickel alloy 65Cr-(31-35)Ni–Ti–V–W depends on the heat treatment mode: the lattice periods of the α-phase (alloy matrix is a solid solution of Ni in Cr) in the hardened and equilibrium conditions are almost the same; level of strength and ductility properties of alloy determines dispersion and amount of γ-soft nuclei released during heat treatment (solid solution of Cr in Ni), its hardness is less than that of α-phase. Quenching from single-phase area from 1250°C and tempering at 800−900°C provides a higher strength than annealed alloy and increases the start temperature of high temperature failure. The nature of the destruction depends on the temperature. The influence of γ-phase is manifested more significantly at temperatures below equicohesive.
