STRESS-RELIEF EMBRITTLEMENT OF AX-140 AND E-11018 WELD METALS,

Abstract

An attempt was made to arrive at optimum stress-relief treatments (maximum relief of residual stress with minimum increase in transition temperature) for AX-140 and E-11018 weld metals. Stress-relief of E-11018 results in acceptable toughness (although softening must be considered), whereas, stress-relief of AX-140 can produce severe embrittlement. A satisfactory thermal stress-relief treatment cannot be specified for weldments involving AX-140. Weld metal properties vary through the thickness of the weld. Center-of-weldment material is not as tough as surface material in the as-welded condition and exhibits a greater susceptibility to stress-relief embrittlement. (Author)
