Abstract Reaction ball milling process was used to prepare Al-SnO₂-MgH₂ alloy powders, then a high thermal stability nanocomposite Al-Sn alloy was obtained by a combination of cold pressing and sintering. The effect of reaction ball milling process on the microstructure and properties were investigated by XRD and SEM. The results show that the SnO₂ in the MA Al-SnO₂-MgH₂ alloy powder, which was produced by a two steps method with the addition of MgH₂, was almost deoxidized into monolithic Sn after sintering at 600 ℃. Meanwhile, the in situ formed Sn exhibits a typical dual-scale structure. In particular, the symbiotic formed Sn and Al₂O₃ were in nano-size and homogeneously distributed in the Al matrix, improving the hardness obviously and resulting in a significantly reduction of friction coefficient and wear volume.
