"淬火鋼(quenched steel)"是金屬材料學中一種經過特定熱處理工藝的鋼材。其核心原理是将加熱至奧氏體化的鋼件以快速冷卻方式(如水、油或聚合物溶液)使其組織結構轉變為馬氏體或貝氏體,從而顯著提升材料硬度和強度。該工藝最早可追溯至公元前1200年的鐵器時代,現代工業中淬火參數需根據鋼材碳含量精确控制,例如中碳鋼(0.3%-0.6%C)的典型淬火溫度為800-850℃。
美國金屬學會(ASM International)的研究表明,淬火鋼的洛氏硬度可達50-66 HRC,比退火狀态提升300%以上,這種特性使其廣泛應用于齒輪、軸承等耐磨部件制造。值得注意的是,淬火後必須配合回火處理以消除内應力,否則可能引發工件變形或開裂風險。根據中國機械工程學會公布的行業标準,汽車變速箱齒輪多采用20CrMnTi淬火鋼制造,其表面硬度可達58-62 HRC,芯部保持30-45 HRC的韌性指标。
“Quenched steel”是冶金領域的一個專業術語,指經過淬火工藝處理的鋼材。以下是詳細解釋:
