Promoting the high load-carrying capability of Al-20Â wt%Sn bearing alloys through creating nanocomposite structure by mechanical alloying

►The sliding wear property of nanostructured Al-Sn alloy was studied. ► Nanostructure promotes load-carrying capability and sliding wear property of Al-Sn alloy. ► Plasticity and strength is predominant in wear resistance at different load, respectively. ► Wear mechanism changes from delamination to plastic flow with increase of sintering temperature.
