A Correlation of Microstructure With Hot-Ductility in the Heat-Affected Zone of Inconel 718.

Increased performance requirements for structural components and the demand for materials with enhanced properties have significantly increased the problems involved in producing sound welds. Due to the high temperatures and steep temperature gradients in the vicinity of welds, high stresses and complex stress patterns are unavoidable. Though process control parameters can be varied to minimize such stresses, cracking may occur in the fusion zone or in the weld heat-affected zone (HAZ). The objective of this study was to obtain a better understanding of hot cracking in the weld HAZ by making a correlation between the HAZ microstructure and the HAZ hot-ductility.
