（这些定义由美国材料与试验学会、美国金属学会、美国铸造协会和SAE指定的热处理术语定义联合委员会编制。）本SAE修订版强调了热处理铁合金中使用的术语，但也包括了本文件末尾的一些非铁定义，以供参考。本术语表无意成为规范，也不应被解释为规范。由于这是一组严格的定义，因此故意省略了温度。

(These definitions were prepared by the Joint Committee on Definitions of Terms Relating to Heat Treatment appointed by the American Society for Testing and Materials, The American Society for Metals, the American Foundrymen's Association, and the SAE.) This SAE revision emphasizes the terms used in heat treating ferrous alloys, but also includes for reference some non-ferrous definitions at the end of the document.This glossary is not intended to be a specification, and it should not be interpreted as such. Since this is intended to be strictly a set of definitions, temperatures have been omitted purposely.
