Abstract Scope |
The microstructure and mechanical properties such as tensile and fracture behaviour of Al 2024 – Ram 2 alloy fabricated through laser powder bed fusion is investigated in this study. Ram 2 alloy was produced by 2 % ceramic addition in Al 2024 matrix. Most of the studies in additive manufacturing of aluminium alloys are currently focused on Al-Si alloys like AlSi10Mg, AlSi12 and literature on LPBF of high strength aluminium alloys is limited. Al 2024 is one of the most widely used alloys for aerospace and automobile applications. Al 2xxx series alloys are difficult to process by additive manufacturing due to solidification-related issues resulting from the thermomechanical cycles during AM processes. To obviate these issues, optimized process parameters were used to fabricate defect-free and dense Ram 2 coupons. Test specimen were printed at longitudinal and transverse orientations. The microstructural characterization of printed samples was extensively performed using TEM, and XRD. |
