GRAIN BOUNDARY SEGREGATION OF IMPURITIES IN METALS AND INTERGRANULAR BRITTLE FRACTURE.

Abstract

The report discusses two investigations of temper embrittlement in low alloy quenched and tempered steel. Part I deals with additive effects of phosphorus and antimony as embrittling impurities in this type of grain-boundary embrittlement. Part II describes efforts to develop a method of determining the degree of segregation of alloys and impurities to grain-boundaries during temper embrittlement. The method under study involves neutron activation analysis of the etchant from etched intergranular fracture surfaces. (Author)
