摘要： A structure (10) for a front section of a vehicle body in a vehicle body (1) comprising a front chamber (3) disposed on the forward side of a vehicle interior (2) is provided with the following: a pair of front side members (11), located within the front chamber, that extend in the longitudinal direction of the vehicle body; a pair of strut towers (16) disposed on either side in the width direction of the front chamber and within which front wheel suspensions are disposed; and reinforcement members (20) that link the top of each strut tower with the front side members that face the strut towers, and that extend between the strut towers and the front side members. This configuration allows a structure for a front section of a vehicle body to be provided that can efficiently improve the rigidity of the vehicle body of an automobile against torsion and against lateral bending, and that can efficiently reduce the weight of the vehicle body by means of thickness reduction using a high-strength steel plate.

摘要： A TRIP-type high strength steel plate having good workability is provided which, while reducing the amount of alloying elements added which increase the production cost, ensures a contemplated retained austenite structure, has good adhesion to zinc plating, and can also be applied to highly corrosion resistant surface treated steel plates. The high strength steel plate having improved workability and plating adhesion is such that a high concentration, i.e., 0.03 to 2.0% by weight, of nitrogen is incorporated, the contents of silicon and aluminum, which form nitride, are preferably regulated respectively to not more than 0.5% by weight and not more than 0.3% by weight, and, in addition, calcium, sodium, magnesium, etc. are optionally added to control the formation of iron nitride, whereby the volume fraction of the retained austenite phase in the metal structure is regulated to 3 to 20% by weight.
