| Abstract: | The physical,mechanical properties and the cutting performances of cemented carbide inserted with rare earth metal elements are studied The results show that,after adding rare earth metal elements into carbides their toughness and bending strength increase, and the tool life of this kind f carbides prolongs The effects of adding Sm,Y and SmPr are better than adding other inserts,and the adding amount exists an optimum range. The mechanism of improving proporties of such carbides has ben analysed in the last port of the paper. |
