| Abstract Scope |
Additive manufacturing offers new microstructure control strategies that can be leveraged to design aluminum alloy compositions with improved fatigue resistance at both ambient and elevated temperatures. Improved elevated-temperature fatigue resistance in Al alloys facilitates lightweighting in various sectors by replacing Ti and steel. In this talk, we will discuss the low- and high-cycle fatigue performance at 20, 200, and 350 °C of a new additively manufactured Al-Ce-Ni-Mn-Zr alloy. The attractive performance of this alloy noted from the comparison to other relevant Al alloys is rationalized based on its unique microstructure enabled by additive manufacturing. The crack nucleation and growth at different temperatures and fatigue modes have been addressed based on the fractographic observations. |
