Abstract:
INTRODUCTION
The reduction of vehicle weight by using light-weight structural alloys such as those based on magnesium, aluminum and titanium for body as well as suspension parts is one
of the most promising ways to reduce fuel consumption and improve driving performance. Superior fatigue properties of the materials are an important requirement for these
applications [1,2]. Since shot peening is known as a low cost finishing treatment that is able to markedly improve the fatigue life of many structural materials such as
steels and cast irons, the effect of shot peening on the fatigue performance of the more expensive light-weight alloys is of particular importance for automotive
applications. In addition to fatigue loading, exterior body as well as suspension components of a vehicle are subjected to aggressive environments, e.g., aqueous NaCl
solutions. Thus, the fatigue performance of these materials in such corrosive environments needs to be studied [3,4].
In the present investigation, potential improvements in high cycle fatigue (HCF) performance of light-weight alloys based on Al, Mg and Ti by shot peening are outlined with
particular emphasis put on the effect of corrosive environments.
