磨损和腐蚀问题是挤压和铸造工艺中的常见现象。本研究使用硬质合金铸模研究了碳对合金机械性能和铁质粘结剂结构的影响,这种硬质合金铸模是一种用于机械零件铸造的组成类似于复合硼化物基硬质合金的新型Mo_2FeB_2。还研究了新型合金的磨损和腐蚀行为。铸模合金的铁粘结剂随合金中残余碳含量(从铁氧体到马氏体)增加而变化,获得具有马氏体粘结剂的合金铸模横向断裂应力和硬度相 Wear and corrosion problems are common in extrusion and casting processes. The present study investigated the effect of carbon on the mechanical properties of the alloy and the structure of the iron binder using a cemented carbide mold, a type of cemented carbide mold used for the casting of mechanical parts similar to the composite boride based cemented carbide New Mo_2FeB_2. We also studied the wear and corrosion behavior of new alloys. The iron binder of the mold alloy varies with the residual carbon content in the alloy (from ferrite to martensite) to obtain the transverse rupture stress and the hardness phase of the alloy mold with the martensitic binder
