Abstract

Un método de producción de artículos compactados, completamente densos de partículas atomizadas de aleación de acero para herramientas, que comprende colocar dichas partículas en un envase deformable, evacuado que prensa isostáticamente dichas partículas dentro de dicho envase a una temperatura elevada para producir un pre-compacto que tiene una densidad intermedia, calentando dicho pre- compacto a una temperatura por encima de dicha temperatura elevada utilizada para producir dicho pre- compacto, y prensando isostáticamente dicho pre-compacto calentado para producir dicho artículo completamente denso.
