The mechanical properties of weldments are evaluated in terms of the heterogeneous microstructural characteristics of weldments. Impression creep data on dissimilar metal weldments and on samples with microstructures which simulate regions within weldments are correlated with theoretical predictions of the deformation behavior of heterogeneous materials. Expressions for predicting weld metal microstructures and properties based on solution thermodynamics and kinetics will be further developed and tested. The phase stability and mechanical properties of high manganese ferrous weld metal alloys with specific additions of Ni, Cr, Al and Si are being investigated.
