Thermal fatigue is an important consideration in many powertrain components, especially in the valve bridge regions in the combustion chambers of a cylinder head. These locations experience some of the highest temperature and load conditions in the component and, as smaller displacement engines are required to generate more power to meet fuel economy standards, those regions will experience even more extreme conditions. Ford Motor Company has developed a thermal fatigue bench test to qualitatively investigate the behavior of alloys used in these applications. This study has examined AlSi10Mg coupons, produced in two different orientations, to determine the influence of build orientation on the fatigue behavior under temperature cycling. These results will be used to help create design guidelines for 3D printing.
