Metal casting is an important manufacturing technology for efficiently producing massive components with complex shape. A large share of industrial castings is made from iron and steel alloys, combining attractive properties and low production cost. Upgrading of properties in cast iron and steel is mainly achieved by alloying and in fewer cases by heat treatment. Molybdenum is an important alloying element in that respect, increasing strength, hardness and toughness. It also facilitates particular heat treatments such as austempering. The paper describes the metallurgical functionality of molybdenum alloying in iron-based castings and demonstrates its effectiveness for applications in the automotive and mining industry.

铸铁和钢中的钼合金化

金属铸造是有效生产具有复杂形状的大型部件的重要制造技术。大量工业铸件由钢铁合金制成，兼具吸引人的性能和较低的生产成本。铸铁和钢的性能提升主要是通过合金化实现的，在少数情况下是通过热处理实现的。在这方面，钼是重要的合金元素，可以增加强度，硬度和韧性。它还有利于特殊的热处理，例如奥氏体淬火。本文介绍了铁基铸件中钼合金的冶金功能，并论证了其在汽车和采矿业中的应用有效性。
