In order to investigate the thermal fatigue characteristic and high temperature deformation behavior of Cu-W artificial lamellar composite, three patterns of thermal cycles which have different ranges of temperature and holding time at maximum temperature were used and the compression tests were carried out at 773K～973K under strain-rates from 5×10-6s-l to 2×10-4s-1. Plastic deformation of Cu layer of the composite and the interfacial sliding between Cu and W layers were observed during the thermal cycles. The result of the compression test suggests that the mechanical property of the composite depends on the atomic structure of the interface between the layers.
