Abstract:

The methods now available for the computation of heat and fluid flow, solidification, microstructural and residual stress development are well advanced. It is logical therefore to proceed to the quantitative relationships between microstructure and mechanical properties so that the variety of models can be consolidated and used directly in the design process. This paper deals with a few of the important mechanical properties and describes some of the innovative treatments under development for the production of better welds or for the exploitation of welding technologies in novel applications.
