Abstract

Deformation and fracture mechanism during tensile testing is investigated for consolidated Fe–Cu alloy. Fe–Cu rapidly solidified powder in which copper is supersaturated is consolidated using groove rolling. Copper content, rolling temperature, and heat exposure condition are varied to obtain samples with various microstructures. The samples are subjected to tensile testing; some tests are suspended to observe the microstructure change during loading. The tensile behavior and the microstructure are correlated based on the obtained stress-strain curves and SEM observation. The difference of the stress-strain curve is explained from the morphology change of the microstructures and the following change of the microfracture behavior during loading.
