Effect of Laser Treatment on γ-Phase Strength Characteristics in Iron–Chrome–Nickel System Alloys
2021
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.
