  • Effects of Mo, Ni-Mo and Cu-Mo Additions on the Matrix of Spheroidal Graphite Cast Iron.

抄録

  Spheroidal graphite cast iron may give high strength, high hardness and sometimes high ductility because of both spheroidalization of graphite and probably modification of matrix. <br>  In the present work, high-carbon and high-silicon cast iron, which apt to poduce spheroidal graphite, has been subjected to the additions of Mo, Ni-Mo and Cu-Mo and treated with Mg. Microstructure and hardness tests have been given to the matrix in regard to the effects of these additions. <br>  Following results have been obtained. <br>  (1) High-carbon and high-silicon cast iron may give super cooled structure in matrix both by the additions of Mo, Ni and Mo or Cu and Mo, and by subsequent Mg-treatment, so-called bainite structure tends to form. And Mg-treatment yields the iron of higher hardness of 30 to 40 HRC than that of non-treatment. <br>  (2) When Si content is varied in the specimens to which Ni and Mo or Cu and Mo are added, hardness of the specimens without Mg-treatment is not so responsible to various amounts of Si additions, while the specimens Mg-treated dicreases in hardness with more Si content.
