|high tempering;高溫回火
高溫回火(High Temperature Tempering)是金屬熱處理工藝中的關鍵步驟,指将淬火後的鋼件加熱至500°C–650°C區間并保溫,隨後以適當速率冷卻的過程。這一溫度範圍高于中低溫回火,可顯著改善材料的綜合力學性能。
從工藝機制分析,高溫回火促使淬火馬氏體分解為回火索氏體,這種顯微組織由鐵素體基體與均勻分布的球狀滲碳體構成。該結構特性使材料在保持較高強度的同時,獲得更好的塑性和韌性平衡。例如,40CrNiMoA合金鋼經高溫回火後,抗拉強度可達900-1100MPa,延伸率提升至12%-15%(數據來源:清華大學材料學院《先進金屬材料》公開課)。
該工藝在工程領域應用廣泛,特别適用于承受交變載荷的關鍵部件,包括:
(應用案例參考:上海交通大學《機械零件失效分析》第3版)
“High temperature tempering”是材料科學中的專業術語,結合“高溫”和“回火工藝”的含義,具體解釋如下:
High temperature tempering(高溫回火):
指在500-650°C溫度範圍内進行的回火處理,常用于中高碳鋼或合金鋼。其目的是:
