| Abstract Scope |
The development of aluminum alloys for additive manufacturing has gained significant attention due to the increasing demand for lightweight and high-strength materials in various industries. However, conventional casting alloys are often not suitable to fulfil this demand, lacking in strength or being susceptible to hot cracking. Taking advantage of the features enabled by the high cooling rates of laser powder bed fusion (LPBF) processes, this work investigates the mechanical response of a novel aluminum alloy containing Cu, Ti, Cr, and Fe with exceptional printability. In static mode, a high yield strength of 462 ± 8 MPa is reached, and an uneven deformation behavior can be observed, which can be explained by the Portevin-Le Chatelier (PLC) effect. Fatigue behavior in the as built state is then put forward with the construction of Wöhler curves, further unrevealing the potential for this alloy for the manufacturing of high loaded components. |
