Abstract
Provided is a high strength cold rolled steel sheet which has a tensile strength of 980 MPa or greater and which exhibits excellent ductility and bendability. The high strength cold rolled steel sheet satisfies a specified component composition, and the structure of the steel sheet at a depth corresponding to a quarter of the sheet thickness satisfies all of (1) to (5) below when measured using specified methods. (1) The areal ratio of ferrite relative to the overall structure is not less than 5% but less than 50 %, with the remainder being hard phases. (2) The areal ratio of a mixed structure of fresh martensite and residual austenite relative to the overall structure is greater than 0% but not greater than 30%. (3) A region in which the concentration of Mn is enriched to at least 1.2 times the concentration of Mn in the steel sheet is present at a proportion of not less than 5% by area. (4) When the fraction of a region in which the concentration of Mn is enriched to at least 1.2 times the concentration of Mn in the steel sheet is measured for 100 sections each measuring 2 µ square, the standard deviation is not lower than 4.0%. (5) The concentration of Mn in a ferrite phase is not higher than 0.9 times the concentration of Mn in the steel sheet.
