摘要：
The choice of suitable methods for establishing of plasticity and formability of new materials has great significance for high quality formed parts manufacturing. The paper is focused on analysis of the dual phase steel DP 450 properties. This steel is used to produce selected parts in automotive industry. The properties are analysed on the base of plasticity and formability evaluation. The paper mentions results of several basic and technological tests such as static tensile tests, Erichsen cup tests, Fukui tests Schmidt cup tests and bending tests. These results are supplemented by microhardness measurements and calculations of strain hardening exponent that were based both on the Ludwik-Hollomon equation and on the strain to necking. The obtained results show that the investigated steel can be applied for forming parts not only for automotive industry.
