|quenching and tempering/thermal refining;調質處理
淬火與回火（Hardening and Tempering） 是金屬熱處理中的核心工藝組合，主要用于提升鋼制零件的機械性能（如硬度、強度、韌性）。以下為詳細解釋：
定義：将鋼材加熱至臨界溫度以上（通常為750–850°C），形成奧氏體組織，隨後快速冷卻（如水淬、油淬），使其轉變為高硬度的馬氏體結構。
目的：顯著提高材料硬度和強度，但會降低韌性，導緻脆性增加。
關鍵點：
權威來源：美國金屬學會（ASM International）指出，淬火是獲得馬氏體的關鍵步驟，其硬度取決于鋼的碳含量。
定義：将淬火後的鋼材重新加熱至較低溫度（150–650°C），保溫後緩慢冷卻，以調整馬氏體組織。
目的：消除淬火應力、降低脆性，提升韌性和延展性，同時保留部分硬度。
關鍵點：
權威來源：劍橋大學材料系研究顯示，回火通過碳化物析出細化晶粒，優化機械性能。
淬火與回火常連續進行：
實例：汽車發動機曲軸需高抗疲勞強度，通過淬火+高溫回火（調質處理）實現。
數據支持：美國能源部研究證實，經調質處理的4340鋼，抗拉強度可達1000 MPa以上，延伸率提升至12%。
權威參考：
“Hardening and tempering”（調質處理）是金屬熱處理中的關鍵工藝，主要用于改善材料的綜合力學性能。以下是詳細解釋：
