Texture and magnetostriction studies in Bridgman solidified Ho0.85Tb0.15Fe1.95 alloys

This work describes the evolution of texture in anisotropy compensated Ho0.85Tb0.15Fe1.95 alloy which was conventionally cast and directionally solidified at four different growth rates by adopting modified Bridgman technique. The development of texture as a function of solidification rate has been investigated by analyzing the experimental X-ray pole figures. A strong 〈3 1 1〉 texture component has been observed for the sample solidified at lower growth rate and mixed texture components of 〈3 1 1〉, 〈112〉, 〈3 3 1〉  〈5 3 1〉 and 〈1 1 0〉 for the samples solidified at higher growth rate. Consequently, larger magnetostriction has been observed in the sample solidified at lower growth rate than in those solidified at higher growth rate.
