我国硬质合金起步虽晚，但发展迅速。目前，硬质合金模具基本上已系列化和标准化。从近几年发展情况来看，我国硬质合金模具的研究和设计的理论已更深入也更科学，应用也更广泛。

在开发新型硬质合金材料上，前几年以铁镍代钻为热门。如湖南省冶金材料所开发的相当于YG、YG20、YG25的高度韧性硬质合金，在用于冷镦模、冷挤压模等方面收到较好的效果。

近几年来新的研究热门是细晶、超细晶，甚至纳米晶硬质合金和梯度硬质合金。梯度硬质合金又有成分梯度、结构梯度等，此外也有用金属熔液渗透处理方法来生产梯度硬质合金的，如梯度硬质合金顶锤等。

Our Carbide started late, but rapid development. Currently, carbide die basically serialization and standardization. In recent years the development of the situation, the theoretical study of carbide tooling and design has a deeper and more science, applied more widely.

In the development of new alloy materials on behalf of a few years ago to drill for the hot iron and nickel. Metallurgical materials such as Hunan province developed the equivalent of YG, YG20, YG25 the strength and toughness of cemented carbide, received good results in for cold heading die, cold extrusion die and so on.

In recent years, new research is popular fine grain, ultra-fine grain, and even gradient nanocrystalline carbide and carbide. There are gradient cemented carbide composition gradient, gradient structure, in addition to the molten metal is also useful to produce osmotic gradient cemented carbide processing methods, such as the top of the gradient cemented carbide hammer.
