Abstract
IN the course of investigations to assess the factors controlling the embrittlement of steels, a wide variety of steels of commercial origin has been studied. It was found that the Charpy impact transition ranges of all the steels were raised—although to varying extents—if the steels were exposed at 450° C. for lengthy periods. In many instances the transition range still remained below room temperature after exposure at 450° C., and the steels were not, therefore, brittle at room temperature. Nevertheless, it was apparent that an embrittlement mechanism was operating at 450° C. in all the steels.
