摘要
通过对 KMTBNi4Cr2合金热处理试验发现 ,铸态下 5 5 0℃ +2 75℃回火处理后的性能优于国标 GB82 6 3- 87规定的 45 0℃ +2 75℃回火后的性能 。
A series of experiments on heat treatment process of KMTBNi4Cr2 alloy show that the character of casting KMTBNi4Cr2 alloy after temptering process at 550℃+275℃ is better than the character at 450℃+275℃ prescribed in GB 8263 87,and the reason is discussed.
