Tribotechnical properties modification of Al-Sn alloys by ECAP
The influence of ECAP on tribotechnical properties of Al-Sn alloys was investigated. It was established that their wear rate under dry friction on steel is reduced up to 18 ± 2% after pointed treatment while the friction coefficient does not depend on the ECAP numbers.
Recent Advances on Al-Sn Alloys with Ternary Alloying Elements
Al-Sn alloys are preferred for bearing materials where an excellent lubricity with proper wear resistance is necessary. In the current paper, the key issues and improvements of Al-Sn-X (X=Bi, Mg, Si, Cu, Pb) alloys are outlined. Effect of ternary alloying element (X) on microstructure, mechanical and tribological properties for Al-Sn alloys are reviewed in brief. Implementation and further development of Al-Sn-X alloys are to be underway.
A high-strength, high-conductivity Al–Ti deformation processed metal metal matrix composite
Abstract An 80 vol.% Al–20 vol.% Ti composite was produced by powder metallurgy and deformation processing. Axisymmetric deformation processing to a true strain of 13.9 produced a composite with sub-micron Ti filaments (textured with the hexagonal close packed 〈 10 1 0 〉 direction parallel to the specimen's cylindrical centerline) in an Al matrix. The ultimate tensile strength of the composite was 890 MPa, and its electrical resistivity was 43 n Ω  m, which is believed to be a higher ratio of ultimate tensile strength to resistivity than the ratios in any commercially available Al alloy. Strength and resistivity were unaffected by a 86 000s anneal at 473 K. The composite's Al and Ti react to form Al 3 Ti at 600 K.
