Effect of Heat Treatment on Microstructure of Continuous Unidirectional Solidified Cu–Ni–Sn Alloys. After annealing at temperature of 850°C for 30?min, it was found that the composition of the alloy began to become uniform and the solutes gathered at the grain boundaries diffused into the columnar grains.作者: Accomplish 時(shí)間: 2025-3-23 01:01
