Abstract

A laminated composite consisting of an ultrahigh carbon steel (UHCS) and an 8Ni-2Si iron interleaf material can be selectively heat treated without carbon diffusion between adjacent layers. This desirable attribute leads to a low ductile-brittle transition temperature (DBTT) of about 163K ( − 110°C) after selective heat treatment. This result is a consequence of notch blunting from the presence of the sharp interlayer boundary and the tough interleaf material. Based on Charpy notch impact results of selectively heat-treated UHCS composites containing 8Ni-2Si iron and other interleaf materials, it is concluded that the DBTT is principally a function of the notch-toughness of the interleaf material.
