Abstract

The two-way shape memory effect with reversible compressive strain up to 5.1% and high cyclic stability is obtained for Ni₄₄Fe₁₉Ga₂₇Co₁₀ (at.%) single crystals by stress-induced martensite aging at 398 K for 1–3 h, under 650 MPa. 100 cycles of thermal treatment at temperatures not exceeding aging temperature, do not affect the temperature of the martensite formation, and reversible strain reduces merely by 0.4%. Thermal cycling with aging overheating significantly decreases reversible strain down to 1% due to the austenite stabilization.

Ni44Fe19Ga27Co10 单晶中双向形状记忆效应的热稳定性和循环稳定性

在 650 兆帕下，通过在 398 开氏度下 1-3 小时的应力诱导马氏体时效，Ni44Fe19Ga27Co10 (at.%)单晶获得了具有高达 5.1%可逆压缩应变和高循环稳定性的双向形状记忆效应。在不超过老化温度的条件下进行 100 次热处理不会影响马氏体形成的温度，可逆应变仅降低了 0.4%。由于奥氏体稳定化，老化过热的热循环可将可逆应变显著降低至 1%。
