Langmuir, Rev. 2021 by the U.S. Secretary of Commerce As the aging proceeds, the secondary -phase grows up and merges; With the increase of the aging temperature, the secondary -phase gradually increases. It is heated to above the recrystallization temperature, deformed by 40% to 85%, then quenched quickly, and then subjected to conventional aging heat treatment. This difference is due to the slow cooling rate of AC, and the p phase in the alloy can fully grow during the cooling process (causing the p phase content in the alloy to increase and aggregate growth under AC conditions). Database and to verify that the data contained therein have E/(2*t2) + G We can create a custom cross-platform; web-based one build for every device solution.
