内容記述 | The deformation of bearing steel JIS SUJ2 specimens under the repeated blow is studied. The size of the specimen is 5mm x 20mm x 1OOmm. The blow 50kgcm is given through the cylinder on the centre of the specimen on the plane bed. The deformation is measured after 6 x 10^4 and 12 x 10^4 blows. The specimen deforms to convex to the direction given the repeated blow, and no cavity of the blow. The hight deformed from the original plane is 6.0--11.5μ at the quenched and tempered specimen, and 2.2--5.2μ at the sub-zero treated specimen. The hardness at the blow-point of the former specimen becomes 40--50 Hv higher, and 20--40 Hv higher at the latter. The hardened depth of the former specimen is twice as deep as the latter. The author presumes that these differences are caused by the martensite transformation of the retained austenite. | |||||

内容記述 | 特殊鋼にサブゼロ処理を施せば,経年変形に対する安定性を増大することは,既に理論的にも証明せられているが,繰返応力を受ける場合の変形に対する安定性にしても,同様にサブゼロ処理の効果が期待される。 軸受鋼の経年変形については,従来多くの研究が行なわれているが,実際軸受として使用せられるときには,繰返応力しかも衝撃的な応力を受けることを考えて,著者は,サブゼロ処理を加えたいくつかの熱処理方法を施したものについて,繰返衝撃に対する変形状態を研究した。 |
