Abstract: In this paper,the Ni36CrTiAl elastic alloy was aged at 820 and 900℃respectively,and a tensile test was carried on the sample before and after aging.The microstructure and fracture characteristics of Ni36CrTiAl elastic alloy were investigated through microscope observation,SEM analysis,and XRD analysis.Results show that the main phase of Ni36CrTiAl alloy was Ni3(Cr,Al)and the fracture was brittle before aging.A certain amount of Ni3(Ti,Al)phase occurred on the grain boundary of Ni36CrTiAl alloy after aging at 820 ℃,and meanwile a certain amount of dimples appeared on the fracture.The second phase increased and dispersed inside grains after aging at 900℃and the fracture showed ductile fracture characteristics.
