Abstract

The effects of chemical order on the phase stability and magnetic properties of the metamagnetic shape memory alloy Ni45 Co5 Mn36.7 In13.3 were investigated. Alloys quenched from the B2 and L 21 phase regions were found to transform to the L 10 and 6M martensite phases, respectively. For alloys quenched from the B2 region the martensitic transformation starting temperature is about 80 K higher than that for alloys quenched from the L 21 region. The Curie temperature of the parent phase and the magnetization of the martensite phase were both lower for the alloy quenched from the B2 region than those for the alloy quenched from L 21 region.
