Surface hardening and plastic stability of Ti–6Al–4V alloy by cryo-quenching

Ti–6Al–4V alloy was heat-treated at 850 °C followed by air cooling, water- and cryo-quenching. The quenched samples were further work-hardened and plastically stabilised under tension. Interestingly, the surface hardness was more improved by the cryo-quenching, which led to the enhanced formation of...

Zusammenfassung:Ti–6Al–4V alloy was heat-treated at 850 °C followed by air cooling, water- and cryo-quenching. The quenched samples were further work-hardened and plastically stabilised under tension. Interestingly, the surface hardness was more improved by the cryo-quenching, which led to the enhanced formation of complex α′ martensite structure at the outermost surface than the water-quenched sample.
