| 内容記述 | In alloy steel constructions, temper embrittlement arises occasionally when they were used at 725K for as long as 10000h. Such the temper embrittlement is usually difficult to be artificially reproduced in laboratory, and hence, some rapid experimental procedure is required. Step-cooling heat treatment which was proposed by G. C. Gould has been used conventionally as a rapid procedure. However, effectiveness of this method is not yet analyzed from the metallurgical point of view. The present authors discussed the Gould's original paper reffering their own experimental results, and proposed the following points. (1)Gould's step-cooling is valid mainly for Ni-Cr-Mo-V steels in which temper embrittlement aeises in a shorter time range but not valid for Cr-Mo steels in which it arises in a long time range. (2) Temper embrittlement can be reproduced in Cr-Mo steels if some modified step-coolng processes which are made on the basis of the results of isothermal tempering, are applied. (3)The present authors proposed a new method that the beginning time period of temper embrittlement at 725K is estimated from those of the higher temperatures. | |||||||||||||
