摘要

A heat treatment has been developed to increase the toughness of 12 alpha Cr steels without lowering the yield strength. The heat treatment consists of austenitizing for 1 h at 1300 K, oil quench, austenitizing for 1 h at 1150 K, oil quench and temper for 8 h at 900 K with an air cool. Optical and scanning electron microscopy showed that failure mode changed from grain boundary fracture to quasi-cleavage. Transmission electron microscopy showed that the morphology and distribution of the carbides were changed from small lamellar-type carbides which gave low energy failures to large rounded carbides at the prior austenitic grain boundaries which gave high energy failures.
