Micro & Nano Mechanical response of TRIP Steels in Bending and Tension
Backgroundand relevance
TRIP (Transformation Induced Plasticity) steels are one of the newest and most exciting materials being developed by the steel industry. In relation to other advanced high-strength steels, these steels exhibit better ductility at a given strength level. Because of exceptional mechanical response, TRIP steels can be used to produce more complicated parts than other high strength steels allowing the automotive engineer more freedom in designing parts to optimize weight and enhance overall safety of an automobile. Althoughthese steels exhibit extremely good ductility in tension, it is still not clear as to why they fail at lower elongations during the deep drawing processes. In general, deep drawinginvolvesnot only tensile stresses but also includes compressive and shear components. Ideally, bending provides a stress state in which a combination of all the above stresses becomes operative and could provide us with vital clues about the changes in the transformational behaviour happening inside these materials.

About us
This cutting-edge research is the product of a close collaboration between the steel industry(TATA Steel) and excellent academic research centers at the TU Delft (the Kavli Institute of Nanoscience andthe Materials Science Department).The HREM and MSD groups where these studies will be performedhavea vastexperiencein TEM/SEM research. Recently, an exciting phenomenon of austenite grain rotation was also revealed during the deformation of these steels [1].As a member of our group you will not only be able to benefit from our experimental experience but also will be a part of very cool team of PhD and master students!
