Popis:	Effect of Pr6O11addition on the microstructure and properties of superfine-grained WC-Co cemented carbide was studied by experiments. The experimental results show that Pr6O11can inhibit WC grain growth. In addition, the η phase firmed when the content of Pr6O11was more than 0.8%. When Pr6O11dopant amount is 0.4% and 0.8%, the alloy has the best bending strength and the best hardness respectively.
