- Abstract
Vehicular equipments and parts made with high strength materials can provide low weight, fuel economy and better performance to vehicles. The main key is thickness reduction obtained as consequence of improved steel strength used in these components. In that way, there are several developments aiming materials replacement to improve vehicular performance. New alloys, based on aluminum and titanium, and developments on new micro-alloyed steels (HSLA) and transformed/additional phase steels (Duplex, Dual-phase, TRIP e TWIP), have been used for improve vehicular performance. However, there are important considerations need to be done to make this replacement possible: manufacture issues, practical final use of these equipments and parts, and economical viability of course. This work presents the main considerations to make practical materials replacement of truck components and case studies exemplify the ideas presented here. In the replacements cases showed, success was obtained not only by weight savings, but additionally by increase of final structure resistance, with minimum impact on manufacturing and besides, with lowering final cost of product.
