过渡金属硼化物的实验研究现状与趋势

Experimental Development Status and Trend of Transition Metal Boride

过渡金属硼化物很有可能成为新一代的超硬材料而成为材料领域的研究热点。介绍了过渡金属硼化物块体材料主要的制备方法,总结了部分过渡金属硼化物的结构和性能。目前实验研究制备的过渡金属硼化物硬度值与理论研究的理想值还有一定差距,需进一步改进材料的设计思路和制备方法。展望了过渡金属硼化物的发展趋势。

The transition metal boride is likely to be a new generation of superhard material and becomes a hot research topic in the field of materials. The main preparation methods of transition metal boride bulk material are introduced, and some of their structures and properties are summarized. There is still a gap between the hardness value of experimental study and the value of theoretical research. So the design and preparation methods should be improved in the future. And the development trend of transition metal boride was prospected herein.
