IMPROVING THE PLASTICITY OF SLABS OF STAINLESS STEEL WITH THE AID OF RARE-EARTH ELEMENTS,

Abstract

The introduction 0.1 to 0.2% cerium during the casting of an austenite and an austenite-ferrite stainless steel was found to result in improved plasticity at high temperatures both for the cast and the forged metal. Metallographic examinations revealed that the addition of cerium in such amounts reduced the microscopic nonuniformity of the steel, strengthened its grain boundaries, and inhibited the embrittling of nonmetallic inclusions by transforming them into higher melting and more plastic compounds.
