AbstractElectron beam (EB) weldments of 17-4 precipitation hardening (PH) martensitic stainless steel (SS) consisted of a series of distinct yet very narrow heat-affected zones (HAZ) with different microstructural characteristics (composition, fraction and/or size of precipitates, phases and grains). Considering the limited size of each HAZ, shear punch testing (SPT) offers a practical solution for evaluating the mechanical and fracture properties of individual regions within the weldment. This paper describes the use of SPT to determine the variation in the tensile strength (yield and maximum), ductility and strain hardening properties of different regions of the weldment and relate them to the microstructural gradient observed in each of them.
