fatigue in the plastic rangeとは 意味・読み方・使い方

To provide a method for manufacturing a track member with which the hardness in a range including a rolling surface is enhanced sufficiently while suppressing manufacturing cost from rising, a sufficient service life to the rolling fatigue is secured by imparting the high resistance to the rolling fatigue, and the hardness in a plastic deforming range can stably be controlled.例文帳に追加

製造コストの上昇を抑制しつつ、転走面を含む領域の硬度を十分に高くするとともに、転動疲労に対する高い抵抗性を付与して十分な転動疲労寿命を確保し、かつ塑性変形する領域の硬度を安定して制御可能な軌道部材の製造方法を提供する。 - 特許庁

To provide a rolling shaft excellent in fatigue resistance and hard to develop plastic deformation by securing retained austenite quantity necessary to the surface layer on the rolling surface while keeping hardening depth into the suitable range.例文帳に追加

焼入れ深さを適正範囲に維持しつつ転動面の表面層に必要な残留オーステナイト量を確保することで、耐疲労性に優れ、塑性変形の生じにくい転動軸を提供する。 - 特許庁
