The results are as follows; the yield and tensile strength of plates with a thickness of 1.5 mm are higher than that of plates with a thickness of 6 mm. The yield strength also increased and the tensile strength tended to decrease with an increase in tensile speed. This phenomenon is related to the quantity of martensite phase contained in the unstable austenite phase, which is considered to depend on the temperature during tensile testing.}, pages = {67--71}, title = {2相型ステンレス鋼薄板の引張特性と組織}, volume = {22}, year = {1998} }
