Auto body makers are now under great pressure to reduce the vehicle weight and fuel consumption, because of worldwide environmental concerns. In this situation dual-phase steels, especially TRIP (Transformation Induced Plasticity) steels, might be a potential candidate to be used in automobile and truck industries. With the use of cheaper alloying elements like Si and Mn, these steels give much higher strength compared to conventional steels. Moreover, they can provide further strengthening effects during crash events due to stress induced phase transformation and thus ensure more safety for both auto bodies and passengers. In this research work, tensile and fatigue tests were carried out at room temperature in air. After mechanical tests, fracture surfaces were observed by scanning electron microscopy and the proportion of phase (retained austenite) transformation was measured by X-ray and Neutron diffraction techniques. The unique behavior of TRIP steel will be described on the basis of experimental results and the prospects of this steel will be discussed in reference to the properties of other conventional high strength steels used for auto bodies.
