Novel Trip Steel – Characterization, Impact Test and Comparison with Existing Trip Steels

Abstract

4 TRIP steels were produced by use of an induction furnace with controlled atmosphere and vacuum, one of which having a completely new chemical composition with the purpose of obtaining an increased reaction during impact when compared to the other, already documented, steels. This study follows the heat treatment used in order to obtain the TRIP effect in the produced steels and the reaction that the steels exhibit when submitted to an impact test used to simulate a car crash at approximately 60 km/h. The preparation of the samples for both characterization and testing follow standard procedures in terms of analysis. The crash-like tests were performed by using an INSTRON 9340 Ceast which generated an impact energy of 18J. The comparison between the different types of TRIP steels helps to determine the best application of the purposed steel in the automotive industry.
