Ultrafine microstructures make superhard materials harder

As advanced tool materials, diamond and cubic boron nitride （cBN） play a vital role in the modern processing industry. Nonetheless, each material has some intrinsic drawbacks, such as the interior thermal stability of diamond and the relatively low hardness and toughness of cBN. A simultaneous impro...

Description
Summary:As advanced tool materials, diamond and cubic boron nitride （cBN） play a vital role in the modern processing industry. Nonetheless, each material has some intrinsic drawbacks, such as the interior thermal stability of diamond and the relatively low hardness and toughness of cBN. A simultaneous improvement in the hardness, toughness, and thermal stability of these materials has long been desired in the scientific and industry communities.
