Abstract

LIGA SINTERIZADA BASEADA EM FERRO E MéTODO DE PRODUçãO DA MESMA. A presente invenção refere-se a uma liga sinterizada baseada em ferro consistindo, em % em massa, de 2,5 a 3,5 % de Or, 0,4 a 0,6 % de Mo, 0,5 a 1,5 % de Cu, 0,4 a 0,6 % de C, e o balanço de Fe e impurezas inevitáveis, e a liga sinterizada baseada em ferro tendo uma estrutura endurecida como sinterizado. A estrutura endurecida consiste em uma de uma fase martensítica ou uma estrutura mista de 2 a 20 % de razão de área na seção transversal de uma fase bainítica e o balanço de uma fase martensítica como uma matriz exceto os poros.IRON-BASED SYNTERIZED ALLOY AND PRODUCTION METHOD OF THE SAME. The present invention relates to an iron based sintered alloy consisting of by weight% of 2.5 to 3.5% Or, 0.4 to 0.6% Mo, 0.5 to 1.5%. % Cu, 0.4 to 0.6% C, and the unavoidable Fe balance and impurities, and the iron-based sintered alloy having a hardened structure as sintered. The hardened structure consists of one of a martensitic phase or a mixed structure of 2 to 20% area ratio in the cross section of a bainitic phase and the balance of a martensitic phase as a matrix except the pores.
