Abstract

The present work describes the magnetic properties of Nd1-δ (Fe, Mo)12 Nx melt-spun ribbons which have lower Nd content than the stoichiometric composition. The crystallization temperatures of Nd(Fe, Mo)12 phase with ThMn12-type structure and α-Fe phase are at around 600 and 500°C, respectively. Ndo. 9FenMoo. 9N* ribbon after heat treatment at 900°C for 30 min and subsequent nitriding at 550°C for 4 h exhibits coercivity of 240 kA m-1. The V addition increases coercivity and the highest coercivity of 312 kA m-1 can be obtained with the Nd0.9 (Fe0.98 V0.02)11 ribbon annealed at 900°C for 30 min and nitrided at 550°C for 4 h. It can be concluded that Nd1-δ (Fe, Mo)12 Nx melt-spun ribbons with lower Nd content than the stoichiometric composition show a relatively high coercivity.
