采用变速球磨（SSBM）技术制备碳纳米管（CNT）增强铝基高强韧复合材料，结合低速球磨和高速球磨的机理，实现了联合收割机的片状粉末冶金。LSBM的球-粉碰撞较轻，球形Al粉的扁平化速度较慢，碳纳米管有足够的时间均匀分散在Al片表面，对碳纳米管的损伤较小; HSBM的Al片碰撞和冷焊较强，碳纳米管在焊接后的Al颗粒内部聚集，损伤严重，但片间结合较好。因此，通过SSBM的智能粉末加工，即较长的起始LSBM和较短的后续HSBM，可以实现CNT分散、完整性和界面结合的协调。如所证明的，这样的SSBM在1.5重量% CNT/Al复合材料，但通过LSBM和HSBM制造的那些的两倍和三倍的延展性。
Flake powder metallurgy via shift-speed ball milling (SSBM) was proposed to combine the mechanisms of low-speed and high-speed ball milling (LSBM and HSBM) for carbon nanotube (CNT)-reinforced, strong and ductile aluminum composites. LSBM featured mild ball-to-powder collision and slow flattening of spherical Al powders into flakes, leaving enough time for CNTs to be uniformly dispersed on the surface of Al flakes and causing little damage to CNTs; HSBM featured much stronger collision and cold welding of Al flakes, leading to clustered CNTs within the welded Al particles with serious damage but better inter-flake bonding. Therefore, the coordination of CNT dispersion, integrity and interfacial bonding could be achieved by a smart powder processing of SSBM, namely a longer starting LSBM and a shorter following HSBM. As demonstrated, such SSBM resulted in comparable strength in 1.5 wt.% CNT/Al composites but doubled and tripled ductility as those fabricated via LSBM and HSBM.
