work hardening coefficientとは 意味・読み方・使い方

Assuming that, in a metal material, a stress σ agrees with a product of a work-hardening coefficient R and the n-th power (n is a work-hardening exponent) of a distortion ε in a plastic range, two or more tip vertical angles θ of a conical indentor are set in a plastic domain near a yield point.例文帳に追加

金属材料が、塑性範囲において応力σが加工硬化係数Ｒとひずみεのｎ乗（ｎは加工硬化指数）の積に一致すると仮定し、円錐圧子の先端頂角θを降伏点近傍の塑性領域において２つ以上設定する。 - 特許庁

The titanium copper is a copper alloy containing 2.7 to 3.7mass% Ti and consists of the balance Cu and inevitable impurities, in which a work hardening coefficient is ≥0.1 and the difference in volume resistivity (ρ:μΩcm) before and after heat treatment to water-cool the alloy after heating for 10 minutes at 900°C is 25 to 45.例文帳に追加

Ｔｉを２．７〜３．７質量％含有し、残部がＣｕ及び不可避的不純物から成る銅合金であって、加工硬化係数が０．１以上であり、かつ９００℃で１０分間加熱後に水冷する熱処理前後の体積抵抗率(ρ：μΩｃｍ)の差が２５〜４５であるチタン銅。 - 特許庁
