“…These weaknesses encompass relatively low strength and hardness, inadequate wear resistance, and a lower thermal expansion coefficient [50][51][52]. Furthermore, although aluminum alloys like AlSi10Mg are frequently employed in additive manufacturing, they still fall short of meeting the growing requirements for high-strength and tough aluminum alloys [53,54]. These shortcomings underscore the ongoing pursuit for advancements in aluminum alloy development to address these performance limitations and fulfill the escalating demands of diverse industrial applications.…”

Laser powder bed fusion (L-PBF) stands out as a promising approach within the realm of additive manufacturing, particularly for the synthesis of CNT-AlSi10Mg nanocomposites. This review delves into a thorough exploration of the transformation in microstructure, the impact of processing variables, and the physico-mechanical characteristics of CNT-AlSi10Mg nanocomposites crafted via the L-PBF technique. Moreover, it consolidates a substantial corpus of recent research, proffering invaluable insights into optimizing L-PBF parameters to attain the desired microstructures and enhanced properties. The review centers its attention on pivotal facets, including the dispersion and distribution of CNTs, the formation of porosity, and their subsequent influence on wear resistance, electrical and thermal conductivity, tensile strength, thermal expansion, and hardness. In line with a logical progression, this review paper endeavors to illuminate the chemical composition, traits, and phase configuration of AlSi10Mg-based parts fabricated via L-PBF, juxtaposing them with their conventionally manufactured counterparts. Emphasis has been placed on elucidating the connection between the microstructural evolution of these nanocomposites and the resultant physico-mechanical properties. Quantitative data culled from the literature indicate that L-PBF-produced parts exhibit a microhardness of 151 HV, a relative density of 99.7%, an ultimate tensile strength of 70×103 mm3N.m, and a tensile strength of 756 MPa.
