摘　　要：对经不同工艺热处理的A100钢的力学性能进行了测试;跳过深冷处理的试样虽然获得了残余奥氏体,但经过时效处理后不仅钢的断裂韧性降低,而且屈服强度和其它各项力学性能均下降。The mechanical properties of A100 steel in different heat treatment conditions were measured. Test results revealed that the A100 steel samples without being deepfreezed obtained retained austenite. However, not only their fracture toughness but yield strength and other mechanical properties decreased after being aged.

关 键 词：A100钢 断裂韧性 残余奥氏体 合金碳化物
