Additive manufacturing (AM) has revolutionized the production of high-performance components, particularly in industries like motorsport and aerospace. This study investigates the mechanical properties of AM-produced AlSi10Mg and introduces a novel Al2024-RAM2C alloy, designed to elevate the performance benchmarks of AM aluminum alloys in demanding environments.

In this paper, we discuss double-pulse laser peening (DPLP) as surface enhancement technology. Although single-pulse laser peening (SPLP) has yielded excellent results across various applications, its processing performance and efficiency are limited. The DPLP technique involves two laser pulses with a controlled irradiation interval and intensity, enhancing laser absorption through the plasma plume and generating high-amplitude laser-induced shock waves.
