1Friction stir welding of carbon nanotubes reinforced Al-Cu-Mg alloy composite plates显示文摘Carbon nanotubes(CNTs) reinforced Al-Cu-Mg composite plates of 2.2 mm in thickness after extrusion and T4 treatment were joined by friction stir welding(FSW) and the joint efficiency reaches 87%. There was no precipitate in both heat-affected zone(HAZ) and nugget zone(NZ) as a medium rotation rate of 800 rpm and a relative high travel speed of 100 mm min-1were used. In the NZ, FSW disarranged the alignment of CNTs to random orientation and dispersed CNT uniformly. The orientation of CNTs perpendicular to the tensile direction and the possible dissolution of solute clusters made the HAZ become the weakest zone in the joint leading to the failure in the HAZ.Ke Zhao Zhenyu Liu Bolyu Xiao Zongyi Ma 2017Journal of Materials Science & Technology2017,33,9:2
2Wear Behavior of the Uniformly Dispersed Carbon Nanotube Reinforced 6061Al Composite Fabricated by Milling Combined with Powder Metallurgy显示文摘The uniformly dispersed carbon nanotubes(CNTs) reinforced 6061Al composites(CNT/6061Al) with diff erent CNT concentrations were fabricated by powder metallurgy technology. It was found that the friction coe ffi cient as well as wear rate decreased fi rst and then increased as the CNT concentration increasing under 15 N as well as 30 N, and the minimum wear rate was achieved at the CNT concentration of 2 wt%. Adhesive wear and abrasive wear were the dominated wear mechanisms for the 1–2 wt% CNT/6061Al composites under 15 N and 30 N, while the delamination occurred on the wear surface at 3wt% CNT. As the applied load increased to 60 N, the wear rate of composites increased dramatically. The wear mechanism transformed from abrasive wear to severe delamination wear, accompanied by the generation of wear debris with sharp edge due to the weaker anti-shearing strain capacity of CNT/6061Al composites.Xiaonan Li Zhenyu Liu Zhixin Dai Hui Feng Bolyu Xiao Dingrui Ni Quanzhao Wang Dong Wang Zongyi Ma 2022Acta Metallurgica Sinica(English Letters)2022,35,11:0
