我國硬質(zhì)合金起步雖晚，但發(fā)展迅速。目前，硬質(zhì)合金模具基本上已系列化和標準化。從近幾年發(fā)展情況來看，我國硬質(zhì)合金模具的研究和設計的理論已更深入也更科學，應用也更廣泛。

在開發(fā)新型硬質(zhì)合金材料上，前幾年以鐵鎳代鉆為熱門。如湖南省冶金材料所開發(fā)的相當于YG、YG20、YG25的高度韌性硬質(zhì)合金，在用于冷鐓模、冷擠壓模等方面收到較好的效果。

近幾年來新的研究熱門是細晶、超細晶，甚至納米晶硬質(zhì)合金和梯度硬質(zhì)合金。梯度硬質(zhì)合金又有成分梯度、結(jié)構(gòu)梯度等，此外也有用金屬熔液滲透處理方法來生產(chǎn)梯度硬質(zhì)合金的，如梯度硬質(zhì)合金頂錘等。

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.
