Abstract
<div class="section abstract"><div class="htmlview paragraph">Strength, creep, and fatigue of the chassis components are greatly influenced by the material used and its manufacturing process. Alloy wheel is one of the critical chassis components manufactured using the casting process. Secondary Dendrite Arm Spacing (SDAS) is one of the important microstructural parameters generated during the solidification stage of the casting process. SDAS has a significant role in altering the mechanical properties and the behavior of the component. Variation in solidification time and alloy composition will have a major impact in SDAS. The combined effect of SDAS with microstructural variations and the strength behavior has not been studied in earlier literature for an alloy wheel.</div><div class="htmlview paragraph">The scope of this study is to perform casting simulation for an alloy wheel, predict the SDAS and capture the variation of mechanical properties (yield strength, ultimate tensile strength &amp; elongation). Further a few casting simulations were carried out by changing the solidification time and alloy composition to predict the variation of SDAS and its relationship with mechanical properties. The effect of SDAS on strength behavior of the wheel is studied by wheel simulation and correlated with test results.</div></div>
