Summary
In introduction, given subject is austenite transformation product-oriented, are mentioned effects of deformation and cooling processes, often from point of view of physic of metals. New information about different material types applied in automotive industry is presented, including production and heat treatment, resp. thermomechanical treatment and mechanical properties. Materials are divided into three developmental generations, including the AHSS types.
