Abstract

a presente invenção descreve um ímã sinterizado de fe-r-b-cu contendo w e sua liga de têmpera. o ímã sinterizado contém uma fase principal do tipo r2fe14b, com r sendo pelo menos um elemento de terras raras compreendendo nd ou pr; a borda do grão de cristal do ímã de terras raras contém uma área rica em w acima de 0,004 %at e inferior a 0,26 %at, onde a área rica compreende 5,0% em volume ~ 11,0% em volume do ímã sinterizado. o ímã sinterizado utiliza uma quantidade menor de cristal de fixação de w para segregar a migração da borda do grão fixado nas bordas dos grãos de cristal, para impedir eficazmente o crescimento anormal dos grãos e obter uma melhoria significativa. a borda do grão de cristal da liga de têmpera contém uma área rica em w acima de 0,004 %at e inferior a 0,26 %at, e a área rica em w compreende pelo menos 50% em volume das bordas dos grãos de cristal.
