Microstructure and Properties of Ferrous Alloy Weldments. Progress Report, January 1, 1985-December 31, 1985.

摘要

The microstructures and properties of new compositional grades of multipass austenitic weld metal for low and high temperature applications are being evaluated. Alloy modifications, which include substitutions for chromium, are being considered. Expressions for predicting as-solidified weld metal microstructures are being extended to include the effects of composition gradients. The effects of compositional and microstructural gradients on the thermal stability and mechanical properties of the modified austenitic weld metals are being evaluated in both single and multipass weldments.
