Grain growth kinetics of tb18 titanium alloy
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 … WebThe technological importance of grain growth stems from the dependence of properties, and in particular the mechanical behaviour, on grain size. In materials for structural application at lower temperatures, a small grain size is normally required to optimise the strength and toughness.
