从技术角度来看，硬质合金是最成功的复合材料之一。本文综述了硬质合金中各组分（过渡金属碳化物和铁族金属）及其相互作用的物理和化学方面，着重从材料科学的观点出发，讨论了那些已引起技术兴趣的组分。晶体结构和相关系进行了详细讨论。组件的相互作用（润湿，残余应力）和一些微观结构方面（尺寸，邻接，和形状）也被处理。这些基本原理是了解硬质合金生产工艺和性能的基础。
Cemented carbides are, from a technical point of view, one of the most successful composite materials. The physical and chemical aspects of the components (transition-metal carbides and iron-group metals) and of their interaction in hardmetals are reviewed with emphasis on the materials science point of view focusing on those compositions which have gained technical interest. Crystal structures and phase relationships are discussed in detail. The interaction of components (wetting, residual stresses) and some microstructural aspects (size, contiguity, and shape) are treated also. These fundamentals are the basis of understanding the production processes and the properties of cemented carbides.
