2840 磁気吸着力によるステンレス鋼における加工誘起マルテンサイトの測定(S37-4 非破壊評価とモニタリング(4),S37 非破壊評価とモニタリング)
詳細
Volume fraction of deformed-induced martensite in stainless steel can be commonly measured by X-ray diffraction method or magnetic permeability method. In this study, a novel method of measurement of deformation-induced martensite using magnetic contact holding force is proposed. Trials with the measurements were carried out on a prototype measuring system. The results of the measurements in SUS301 and SUS304 stainless steels are discussed in terms of deformation and volume fraction of martensite.
