The Nd10Fe84-xB6Inx(x=0,1) ribbon magnets were prepared with the melt-spun method. Influences of boundary feature on exchange coupling and hardening were investigated by means of indium addition and evaporation. It was found that hoth coercivity and remanence were affected by the grain boundary but in quite different way. Some boundary features affect hardening remarkably, while others strongly influence the exchange coupling.
