In this study, the magnetic properties of a single martensite particle were investigated using type 304 stainless wire, which can reduce the number of crystal grains per unit area. First, the magnetization curve of wire specimens with different martensite fractions was measured by a SQUID magnetic flux meter. Then, the coercivity and susceptibility parameters were evaluated from the magnetization curve and factors contributing to these parameters were discussed. It was found that the coercivity values along the long and short axes of wire specimens with a diameter of 0.4 mm increased and subsequently decreased with an increase in the martensite fraction. Further, the susceptibility values of the same specimen along the long axis increased and along the short axis decreased with increasing martensite fractions. The results indicate that the coercivity and susceptibility of a martensite particle are affected by the size of variant clusters and the shape anisotropy of the martensite particle.

This paper was presented at the 64th Annual Conference on Magnetism and Magnetic Materials.
