摘要：

Small Punch Tests were performed on samples made of austenitic 316L steel, pre-exposed in liquid lead, under temperature conditions of interest for the ALFRED demonstrator. The Small Punch Test produces a force-deflection curve, from which information about the elastoplastic deformation behaviour is extracted. The test specimens were analyzed microscopically by considering the fracture surfaces and the specimens before and after exposure to liquid lead. The data obtained from the tests was processed in MATLAB to identify the material parameters for each sample. The liquid lead effect on candidate structural materials for the ALFRED demonstrator is highlighted. © 2024, Politechnica University of Bucharest. All rights reserved.
