【摘要】：研究了K465合金熱處理后的顯微組織和力學性能。結果表明,合金熱處理后,枝晶干處的γ'相呈立方狀、體積分數為62%,同時還析出了細小點狀碳化物,鑄態(tài)MC碳化物轉變?yōu)镸6C。高溫時效熱處理結果表明,合金經1 000℃/500 h和1 100℃/100 h后,析出富集W和Mo的針狀和棒狀二次析出相;1 000℃條件下,隨著時間的延長,二次析出相的數量逐漸增多;溫度的升高可促進二次相的析出。
[Abstract]:The microstructure and mechanical properties of K465 alloy after heat treatment were studied. The results show that the 緯 'phase in the dendritic stem is cubic after heat treatment, and the volume fraction is 62. At the same time, the fine point carbide is precipitated, and the as-cast MC carbide is transformed into M6C. The results of high temperature aging heat treatment show that after 1 000 鈩，
