interstitial distanceとは 意味・読み方・使い方

This manufacturing method comprises ageing the endless ring made from 18%-Ni maraging steel to a hardness of 500-700 Hv, and then nitriding it so that a surface nitrogen concentration may be 0.5% or more, so that a nitrogen interstitial depth may be 20-50% of a distance to a center of board, and so that the compressive residual stress may be 600 MPa or more.例文帳に追加

１８％Ｎｉ系マルエージング鋼からなる無端リングを５００〜７００Ｈｖの硬さに時効熱処理したのち、表面窒素濃度が０．５％以上、窒素の浸入深さが板厚中心までの距離の２０〜５０％、圧縮残留応力値が６００ＭＰａ以上となるように窒化処理を施す。 - 特許庁
