固溶处理温度对D667钢性能的影响

研究了固溶温度对D667钢性能的影响。结果表明，D667钢固溶温度在1000℃以下时，其延伸率有所提高，但抗拉强度没有明显下降；固溶温度在1000℃～1060℃范围内，试验钢的抗拉强度呈下降趋势，延伸率也保持在高水平线上；固溶温度在1060℃以上，抗拉强度加速下降。D667钢固溶温度在1000℃～1060℃范围内时，可以获得较好的强度和韧性，满足技术要求和各项使用要求。

Effect of Solution Treatment Temperature on the Property of D667 Steel

The effect of solution temperature on the properties of D667 steel was studied.The results show that the elongation of D667 steel increased obviously when solution temperature was under 1000℃,but no significant drop in tensile strength;when solution temperature was in the range of 1000～1060℃,the tensile strength of the test steel tended to decline and the elongation also main tained at a high level;when solution temperature was above 1060℃,the tensile strength drop quickly;when solution temperature was in the range of 1000～1060℃,good strength and toughness could be obtained,which meet the technical requirements and the service requirements.
