| 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 HASS types. |
| Learning Outcomes of the Course Unit |
|---|
| To give students information about different material types on iron base, which are used the most frequently in automotive industry, possibilities of treatment and control of final microstructure, resp. optimised properties and simultaneously to show physical heart of running internal processes during heat, resp. thermomechanical treatment of given steel types. |
