在材料科学和工程领域,tempering temperature(回火温度) 是一个关键的热处理工艺参数,特指将淬火后的金属材料(尤其是钢)重新加热到低于其临界温度(Ac1) 的某一特定温度范围,并保温一段时间后冷却的过程。这个温度的选择直接决定了材料最终的性能,如硬度、强度、韧性、延展性和残余应力的消除程度。

温度范围与组织性能关系:
关键影响因素:
Tempering Temperature 是材料热处理工艺中一个至关重要的控制参数。它不是一个固定值,而是一个根据材料类型、初始状态(淬火后)以及最终期望的性能(硬度、强度、韧性等组合)来精确选择和控制的温度范围。通过科学地设定回火温度和时间,工程师能够“定制”金属材料的性能,使其满足各种复杂工程应用的需求。

关于“tempering temperature”的解释需从两个单词拆分理解,并结合具体语境分析:
基本含义
Tempering是动词“temper”的现在分词形式,在工业领域特指金属热处理中的回火工艺,即通过加热和冷却调整材料性能(如降低硬度、增加韧性)。
延伸含义
在非工业语境中,可表示“调和”或“使缓和”,但使用频率较低。
词性与用法
Different materials require different tempering temperatures.(不同材料需要不同的回火温度)。
其他含义
在工业领域,该词组指回火工艺中设定的特定温度,直接影响材料最终性能。例如:
“Tempering temperature”是金属加工术语,强调回火过程中的温度控制。日常使用中需根据语境区分“temperature”的可数性,而“tempering”则多与工业处理相关。
