Abstract

A study is performed of the effect intense laser heating has on the strength characteristics of the γ‑phase in iron–chromium–nickel alloys. We show that using laser radiation to heat the initial α-phase to the temperature of the α → γ transformation produces a γ-phase with much higher microhardness and yield stress than those of the equilibrium γ-phase. A possible mechanism of this phenomenon is discussed.

激光处理对铁-铬-镍系合金γ-相强度特性的影响

摘要

对强激光加热对铁-铬-镍合金中 γ 相强度特性的影响进行了研究。我们表明，使用激光辐射将初始 α 相加热到 α → γ 转变的温度会产生比平衡 γ 相具有更高显微硬度和屈服应力的 γ 相。讨论了这种现象的可能机制。
