AN ABRASION RESISTANT SINTERED MEMBER AND METHOD FOR MANUFACTURING THEREOF

摘要

A wear resistant sintered member comprising an Fe base alloy matrix and a hard phase dispersed in the Fe base alloy matrix and having an alloy matrix and hard particles precipitated and dispersed in the alloy matrix. Manganese sulfide particles having particle size of 10 mum or less are uniformly dispersed in crystal grains of the overall Fe base alloy matrix, and manganese sulfide particles having particle size of 10 mum or less are dispersed in the alloy matrix of the hard phase.
