| Abstract | 利用XRD和扫描电镜研究了热处理对一种定向凝固Co基合金微观组织的影响。结果表明:Co基合金的铸态组织主要由Co的固溶体基体、M_7C_3、MC和M_(23)C_6碳化物组成,其中M_7C_3和MC为块状,主要分布在枝晶间,M_(23)C_6呈颗粒状,分布在块状M_7C_3和MC周围。合金经1150℃×4h固溶处理后,大部分块状M_7C_3和MC溶入Co的固溶体基体中,在随后的空冷中析出颗粒状M_(23)C_6。在870℃和970℃时效时,随时效温度的升高和时效时间的延长,合金中M23C6的尺寸逐渐增大。 |
| Other Abstract | The effects of heat-treatment on the microstructure of directional solidification Co-base superalloy were investigated using XRD and SEM.The results show that the microstructure of Co-base superalloy as-cast is composed of Co matrix,M7C3,MC and M23C6.Among them,MC and M7C3 distributes in inter dentrite and M23C6 near the MC and M7C3.After solid solution heat-treating at 1150 ℃ for 4 h,most MC and M7C3 dissolves into Co-base matrix,M23C6 is deposited from Co matrix during following air cooling.When aging at 870 ℃and 970 ℃,the size of M23C6 increases with the increase of temperature and aging time. |
