Abstract

The fcc-to-bcc martensitic transformation in Fe-Co precipitate particles has been induced by applying magnetic field to Cu-Fe-Co alloy single crystals at a range of temperature between 4 K and 300 K. The volume fractions of martensite can be estimated from the values of saturation magnetization of the bulk specimens. The amount of transformation is strongly dependent on the cooling temperature, and reaches its peak at around 77 K. The existence of the peak temperature is explained by considering the antiferromagnetic transformation of fcc Fe-Co.
