Improving the Tribological Properties of Self-lubricating Al-Sn Alloys by their Severe Plastic Processing

摘要

The influence of equal channel angular pressing by route A on the structure and properties of sintered Al-40Sn alloys was investigated. It was founded that the microstructure of sintered alloys very strong correlated with the type of initial powders that, nevertheless, not affects on mechanical properties of sintered alloys. The sintered structure of alloys was transformed in the layered one, using the pressing. It results in the square of interphase boundaries enlarging that gives to Al-40Sn alloys some additional strengthening and wear resistance.
