| Abstract: | Effect of cooling rate during solution treatment on mechanical properties of ZG0Cr17Ni4Cu4Nb steel after aging was investigated.The heat treatment cycle consisted of solution treating at 1040 ℃or1050 ℃,cooling in air,water or oil then aging at 470 ℃,480 ℃,490 ℃,500 ℃,550 ℃ respectively.The results show that the cooling rate during solution treating has great influence on the mechanical properties of ZG0Cr17Ni4Cu4Nb steel,and the most suitable heat treatment process consists of heating at 1040 ℃ for 50 min,oil-cooling,then aging at 490℃ for 3 h and air-cooling,and aging again at 470 ℃ for 4 h and air-cooling. |
| Keywords: | solution treatment cooling aging mechanical Property |
