在材料科學和工程領域,tempering temperature(回火溫度) 是一個關鍵的熱處理工藝參數,特指将淬火後的金屬材料(尤其是鋼)重新加熱到低于其臨界溫度(Ac1) 的某一特定溫度範圍,并保溫一段時間後冷卻的過程。這個溫度的選擇直接決定了材料最終的性能,如硬度、強度、韌性、延展性和殘餘應力的消除程度。

溫度範圍與組織性能關系:
關鍵影響因素:
Tempering Temperature 是材料熱處理工藝中一個至關重要的控制參數。它不是一個固定值,而是一個根據材料類型、初始狀态(淬火後)以及最終期望的性能(硬度、強度、韌性等組合)來精确選擇和控制的溫度範圍。通過科學地設定回火溫度和時間,工程師能夠“定制”金屬材料的性能,使其滿足各種複雜工程應用的需求。

關于“tempering temperature”的解釋需從兩個單詞拆分理解,并結合具體語境分析:
基本含義
Tempering是動詞“temper”的現在分詞形式,在工業領域特指金屬熱處理中的回火工藝,即通過加熱和冷卻調整材料性能(如降低硬度、增加韌性)。
延伸含義
在非工業語境中,可表示“調和”或“使緩和”,但使用頻率較低。
詞性與用法
Different materials require different tempering temperatures.(不同材料需要不同的回火溫度)。
其他含義
在工業領域,該詞組指回火工藝中設定的特定溫度,直接影響材料最終性能。例如:
“Tempering temperature”是金屬加工術語,強調回火過程中的溫度控制。日常使用中需根據語境區分“temperature”的可數性,而“tempering”則多與工業處理相關。
