Title: Characteristics of the weld interface in dissimilar austenitic-pearlitic steel welds

Abstract

The weld interface in dissimilar alloy welds between austenitic and pearlitic steels was observed directly by using scanning and transmission electron microscopy, and energy-dispersive x-ray spectrometry. Two types of weld interface were found in the joints. One was the austenite/martensite-like interface that formed the boundary between the mixed weld metal zone and the partially mixed transitional zone. The other is the martensite-like/ferrite interface that is the true liquid-solid boundary of the joint. These interfaces can exist independently in different joints and can also coexist in one joint, depending on the Cr and Ni contents of the filler metals and alloy in the base metals. The formation mechanism of the weld interface and its effect on the mechanical properties of the welded joint are discussed.
