Room and elevated temperature tensile and fatigue behaviour of additively manufactured Hastelloy X
Abstract
Quasi-static tensile and stress-controlled high cycle fatigue tests of solution heat-treated (SHT) Hastelloy Xmanufactured by electron beam powder bed fusion (PBF-EB) and laser-based power bed fusion (PBF-LB) processwere performed at room temperature and 750 ◦C. Post-fabrication SHT was ineffective in overcoming themicrostructural anisotropy observed within as-built specimens, with the grains still maintaining its columnararchitecture along the build direction. A significant drop in ductility was observed in tensile specimens tested at750 ◦C, which was attributed to the carbide precipitation and grain boundary sliding. Upon investigating theinfluence of microstructural evolution as a function of test duration, a significant increase in precipitation wasobserved with an increase in test duration. A notable decrease in the fatigue strength was observed at elevatedtemperature. The long columnar grain structure within vertically build PBF-EB specimens was found to offerhigher resistance against fatigue at 750 ◦C, owing to its reduced grain boundary area perpendicular to theloading direction. The corresponding fatigue damage mechanisms were investigated via fractographic analysis ofthe fracture surfaces and longitudinal cross-sections of the fractured specimens. Irrespective of the buildorientation and test conditions, the fatigue cracks that resulted in final failure were found to initiate from thespecimen surface. Also, the grain boundary precipitates were found to result in intergranular cracking duringelevated temperature fatigue tests.
