Document Type and Number:
WIPO Patent Application WO/2021/031231
Kind Code:
A1
Abstract:
A hot isostatic pressing process for Ti2AlNb alloy powder, which belongs to the field of powder metallurgy titanium alloys. The process comprises: firstly placing a bag sleeve containing Ti2AlNb powder into a hot isostatic pressing device to undergo a first stage of treatment under low temperature and constant pressure, to densify the material; then continuing to heat to allow the bag sleeve to rise in temperature along with the oven to a hot isostatic pressing temperature T2 and holding the temperature for a period of time to so that the organization of the materials is uniform; and stopping heating and cooling along with the oven to room temperature so as to obtain a Ti2AlNb alloy component.
