前言在毛主席革命路线指引下,模具战线上的技术革命、技术革新运动呈现一派朝气蓬勃、飞跃发展的大好形势。钢结硬质合金以合金钢、工具钢、不锈钢等作为粘结相,以碳化钛或碳化钨作为硬质相,用一般粉末冶金方法和热处理工艺所制取的一组材料。因为它的基体为钢,因为,可以机加工、焊接、热处理、鍛造变形。同时也含有大量的碳化物,故也保留了硬质合金的高硬 Foreword Under the guidance of Chairman Mao’s revolutionary line, the technological revolution and the technological innovation movement on the mold front show a fantastic situation of leapfrog development. Steel bonded carbide to alloy steel, tool steel, stainless steel as the binder phase to titanium carbide or tungsten carbide as the hard phase, with the general method of powder metallurgy and heat treatment process of a system made of a group of materials. Because of its base steel, because it can be machined, welded, heat treatment, forging deformation. At the same time also contains a lot of carbide, it also retains the carbide hard
