| 中文摘要: |
| 国产大飞机及其发动机的自主研制需采用M1 52 合金制造发动机机匣，该机匣盘锻件尺寸大、结构复杂，工作时承受很
大的载荷，对其综合力学性能要求苛刻。为提高M1 52 合金机匣锻件的组织与力学性能水平，需要对其热处理工艺进行系统研究。
通过试验研究了不同的淬火、回火制度对M1 52合金机匣组织性能的影响。采用光学显微镜分析了锻件的显微组织，测试了锻件的
室温拉伸、冲击和硬度。综合分析结果表明：当M1 52合金锻件经1 01 0 ℃淬火，油冷,565 ℃回火，空冷热处理后，可实现强度、韧性
的良好匹配 |

| The engine casing should be made of M152 alloy during independent research on domestic large aircrafts and their engines.
Requirements of the general mechanical properties were rigorous due to large size, complex structure, and great working load of the engine
casing disk forging. The systematic study on heat retreatment technology was necessary for increasing the microstructure and properties of
M152 alloy casing forging. The effect of different quenching and tempering treatments on microstructure and properties of M152 alloy casing
was studied through the experiment. The microstructure of the forging was analyzed by optical microscope, moreover, the room-temperature
tensile, impact and hardness of the forging were tested. The results show that after quenching at 1010益, oil cooling, tempering at 565益and
air cooling, a well matching of intensity and toughness of M152 alloy forging can be reached |
