Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA EL TEMPLADO DE CARTUCHO DE ACEROS SINTERIZADOS SUPERIORES EN ALEACION CON MOLIBDENO. SE PREVE, QUE LOS ACEROS SINTERIZADOS SE ENFRIEN JUSTO DESPUES DEL SINTERIZADO A UNA TEMPERATURA A LA CUAL EL ACERO SINTERIZADO TENGA EL MINIMO CONTENIDO EN HIERRO {GA}, Y QUE A ESTA TEMPERATURA SE SOMETAN LOS ACEROS SINTERIZADOS A UN TRATAMIENTO CON CALOR EN PRESENCIA DE CARBONO.
