摘要：

A study was conducted to investigate the effect of aging treatment on the hardness and impact energy of material. Hastelloy C-276 samples were etched in a solution of 10-12% HCl in ethanol and then examined in scanning electron microscope (SEM). Impact testing of samples was carried with 50J hammer. Hardness of the alloy was measured in three conditions: as-received, solution treated and aged by Rockwell hardness tester (HRB). In general, aging at 850°C raised the hardness and decreased the ductility of the material with the production of Mo rich μ phase.
