    The phenomenon of embrittlement of steels after heating for extended periods of time has been recognized for many years. That the addition of a stress can accelerate this embrittlement has been claimed by some and denied by other investigators. Recently what appears to be a closely related phenomenon, namely the severe weakening effect caused by notches in creep loading, has been reported in a number of German and Swiss papers.
