钢结硬质合金是以碳化钛或碳化钨作为硬质相,以铬钼合金钢作为粘结相,用一般粉末冶金方法压制,烧结,并经退火所制取的。它既具备一般工具钢的可加工性、可热处理、可焊接和可锻性,同时具备含钴硬质合金的硬度(淬火状态)和高耐磨性,近年来在模具上应用十分广泛。一、GT-35钢结硬质合金的化学成分和物理机械性能1.钢结硬质合金的化学成分钢结硬质合金(以下简称合金)是由TiC、Fe、C、Cr、Mo或WC、Cr、Mo、
Carbide carbide is based on titanium carbide or tungsten carbide as a hard phase, chromium-molybdenum alloy steel as the binder phase, with general powder metallurgy method to suppress, sintering, and prepared by the annealing. It has the general tool steel machinability, heat treatment, solderability and malleability, with the hardness of cobalt-containing cemented carbide (quenched state) and high wear resistance, in recent years a wide range of applications in the mold. First, the chemical composition and physical and mechanical properties of GT-35 cemented carbide 1. The chemical composition of cemented carbide cemented carbide (hereinafter referred to as the alloy) is made of TiC, Fe, C, Cr, Mo or WC , Cr, Mo,
