SOLID-SOLUTION POWDER, METHOD TO PREPARE THE SOLID-SOLUTION POWDER, CERMET POWDER INCLUDING THE SOLID-SOLUTION POWDER, METHOD TO PREPARE THE CERMET POWDER, CERMET USING THE CERMET POWDER AND METHOD TO PREPARE THE CERMET
SOLID-SOLUTION POWDER, METHOD TO PREPARE THE SOLID-SOLUTION POWDER, CERMET POWDER INCLUDING THE SOLID-SOLUTION POWDER, METHOD TO PREPARE THE CERMET POWDER, CERMET USING THE CERMET POWDER AND METHOD TO PREPARE THE CERMET
Disclosed are a solid-solution powder, a method for preparing the solid-solution powder, a cermet powder including the solid-solution powder, a method for preparing the cermet powder, a cermet using the cermet powder and a method to prepare the cermet. According to the present invention, the problem of low toughness due to high hardness that conventional cermets (especially TiC or Ti(CN) based cermet) have is resolved because a complete solid-solution phase without core/rim structure is provided to the cermets as a microstructure thereof, and in which further increased the hardness as well as the toughness, thereby substantially and considerably increasing general mechanical properties of materials using the cermet, and thus substituting WC—Co hard material and allowing manufacturing of cutting tools with high hardness and toughness.
