摘要
本文研究了GH99板材在不同热处理制度下的机械性能,制备了一种新型的GH99板材,其900℃下的高温强度可达到400MPa,高温断后伸长率可达到30%以上,具有较好的强度和塑性。
In this paper, the mechanical properties of GH99 plate under different heat treatment systems are studied. A new type of GH99 plate is prepared. Its high temperature strength can reach 400 MPa at 900℃, and its elongation can reach more than 30% after fracture at high temperature. It has good strength and plasticity.
