增材制造耐热铝合金及复合材料研究进展OA

With the rapidly growing demand for lightweight,complex-structured heat-resistant components in the aerospace and advanced manufacturing fields,additive manufacturing(AM)has demonstrated unique advantages in the development of high-performance heat-resistant aluminium alloys and aluminium matrix composites because of its layer-by-layer deposition capability and high cooling rates.This work systematically reviews the current research progress on AMed heat-resistant aluminium alloys and aluminium matrix composites,with particular emphasis on strategies for modifying conventional aluminium alloys,advancements in aluminium-transition metal element alloys,and the development of ceramic particle-reinforced and whisker-reinforced aluminium matrix composites.Furthermore,future research directions aimed at achieving breakthroughs in material performance through precise alloy composition design,innovative AM processes,and synergistic control of multiple physical fields are outlined,providing theoretical guidance and practical references for the further development and engineering application of heat-resistant aluminium alloys and their composites.
