I did not read the file,but I think it may be radiographic test. thanks ,got it, it means room temperature 一般不说room temperature,说 ambient temperature 这里讲的自然时效,在AMS2771就是RM RT is different fromR.T. RT rcaction time, R.T.room temperature. did you read though AMS2771? you got nothing, It's Natural aging in RT, should refer to context AMS Aeronautical Materials specification 航空材料技术规范(美国S.A.E 制订的)
AMS 氨基磺酸胺。

。。。。。。 铸铝热处理一般热处理人员很少接触,我大学毕业后在汽车制造中只是坩埚炉中做少量的有色,80年代还有少量Natural aging , 90年代就不Natural aging ,反正都忘光了。
