中文摘要：研究了不同固溶处理温度对254SMo组织和力学性能的影响。结果表明：254SMo在1150℃以上固溶处理时，组织能充分固溶,力学性能较好；254SMo的析出相比较复杂，主要是σ相和χ相，对钢的性能有重要的影响；在试验的温度范围内固溶处理时，晶粒正常长大，长大激活能152KJ/mol。
英文摘要：The effect of solution treatment on the microstructure and mechanical properties was investigated. The results are as follows:①the precipitates in 254SMo dissolves completely above 1150℃ ，as well as better mechanical properties ②the precipitates below 1150℃ is complex, mainly σ and χ phase ,and affect the properties of 254SMo ③grain grows normally with increasing the solution temperature in the test range. The activity energy (Q) is 152KJ/mol.
