“…One of the metals which prominently used in automotive industry is advance high strength steel (AHHS). The automotive manufacturers are continuously increasing the use of high strength steel in order to comply with the safety norms of different geographic region and also to reduce the weight of the car to make it more fuel-efficient [12]. The Advanced High Strength Steel (AHSS) for the car business highlights both high quality for part thickness diminishment and improved formability for creative new part outlines.…”

The paper describes a work focused on the process of perforation of multilayer advanced high strength steel (AHSS). A numerical investigation has been carried out to analyze in details the perforation process subjected to normal impact by different nose shapes of projectiles. The perforation process has been simulated by the application of 3D analysis using IMPACT dynamic FE program suite. The comparison on failure modes depending on the projectile nose shape have been studied and evaluated. An appropriate constitutive relation was applied to describe the material behaviour of the multilayer target plate. The study covered different failure modes of perforated advanced high strength steel (AHSS) sheet according to different level of impact velocity ranging from 22 m/s to 78 m/s. The blunt projectile impact towards multilayer target plate leads to generation of plug formation and fragmentation while hemispherical projectile impact shows almost similar petals formation between first, second and third layer.

The objective of the study described here is to elucidate the effect of carbon and niobium on the microstructure, precipitation behaviour, and mechanical properties of 0?09C-0?11Ti (%) steel and 0?05C-0?025Nb-0?11Ti (%) steel under ultra fast cooling condition. The strengthening mechanisms are also discussed. The ferrite grains size and the size of precipitates in Ti and Nb-Ti steels were measured respectively. The mechanical properties obtained in Ti steel were similar to Nb-Ti steel with yield stress .700 MPa, elongation .20%, and good low temperature impact toughness. The study underscores that addition of higher carbon content by 0?04% under controlled rolling and ultra fast cooling conditions, we can achieve similar strength in the absence of micro-alloying element, niobium.
