Abstract

In this research, we performed tensile tests, microstructure analysis, and high-cycle fatigue tests of Fe-2%Ni alloy specimen produced by using the metal injection molding (MIM) process. In the microstructure observation results, inhomogeneous ferrite and pearlite were appeared. As a result of tensile tests, the tensile strength and strain rate of the specimen was 605 MPa and approximately 6.0%, respectively, and the hardness of the specimen was approximately 220 Hv. The high-cycle fatigue tests revealed the fatigue limit of the Fe-2%Ni alloy specimen to be 410 MPa. Further, by analyzing the fracture surface, we appraised the tensile and fatigue failure behavior of Fe-2%Ni alloys produced by the metal injection molding.
