摘要：
A novel hybrid material was fabricated from the Al-Ti system using high-pressure torsion up to 50 turns. Microstructural observations revealed intermetallic phases and mixing zones enriched in Ti, consisting of grains of-20 nm within an Al matrix. Microhardness measurements gave values higher than in the HPT-processed bulk aluminium alloy.
