WebJun 1, 2024 · Abstract Titanium and its alloys are extensively used in a variety of high performance applications with the α + β alloy, Ti-6Al-4V, being the most popular. Conventionally Ti alloys in the as-cast condition possess highly coarse prior β grains, whose size is in the order of ~mm. WebOct 4, 2024 · Experimentally determined grain growth data for the Ti alloy are found to follow classical particle-stabilized grain growth kinetics with a temperature dependent …
Grain Growth Kinetics of TB18 Titanium Alloy - rmme.ac.cn
WebThe effect of cold rolling reduction on grain growth kinetics of TB8 titanium alloy, during annealing heat treatment, is investigated systematically. The alloy was cold rolled with reductions of 20%, 40% and 60%, followed by annealing process at 750 °C (α/β field), 800 °C (close to β transition point) and 850 °C (β field) during various time spams. WebResults show that the heat treatment temperature and holding time have significant effects on the β grain growth of TB18 titanium alloys. The β grain size is increased with … is a number prime
