天然金刚石单晶是人们进行地球深部重大科学问题探索的“窗口”。然而,金刚石单晶中的{111}解理,在增加其脆性的同时,也在极大程度上制约了其在钻头、切削工具及耐磨器具等方面的应用;但是多晶金刚石中晶粒随机定向、晶粒
Natural diamond single crystal is one of the “windows” for people to explore major deep-seated scientific problems on Earth. However, the {111} cleavage in diamond single crystal, while increasing its brittleness, also greatly restricts its application in drill bits, cutting tools and wear-resistant appliances; however, the grain size of the polycrystalline diamond Random orientation, grain
