機械構造部品用焼結材料のヤング率について Young's Modulus of Sintered Materials for Structual Machine Parts
Method for determination of Young's modulus of sintered metal materials is dynamic testing method by the longitudinal oscillations of the specimens, which has been provided in the standard of Japan Powder Metallurgy Association JPMA M 10 in March 1997. This paper shows the testing results of Young's modulus of various sintered metal materials for machine parts of the iron base, the stainless steel base and the bronze base materials, which are introduced in Japanese Industrial Standard JIS Z 2550. For example, the specimens of the iron base (6×8×60mm) were made from reduced iron powder, atomized iron powder, electrolytic copper powder, natural graphite powder and carbonyl nickel powder, by compressing with 300-600 MPa and sintering at 1423K for 1.8ks in cracked ammonia atmosphere. Consequently, the values of Young's modulus and relations between the values of Young's modulus and the sintered densities of various sintered metal materials could be obtained.
