Method for manufacturing a motor vehicle component and motor vehicle component

摘要

Producing a metallic motor vehicle component, comprises providing a steel sheet metal plate with a manganese content of 10-30% and a stacking fault energy of 5-50 mJ/m 2>, preferably 10-40 mJ/m 2>, at least partially tempering the steel sheet metal plate to a cold molding temperature of +- 30[deg] C and -250[deg] C, molding the steel sheet metal plate to a sheet component at cold molding temperature for inducing at least partial martensite formation by cold molding method, and removing the steel sheet metal plate. The material of the steel sheet metal plate tends to crystal twinning at room temperature. An independent claim is also included for the motor vehicle component, produced by the above mentioned method, where the motor vehicle component is formed from twinning-induced plasticity steel alloy, where at least partial regions of the component exhibits martensitic structure.
