Abstract

Aluminum alloy composites reinforced with aluminum borate particles (ABp) were thermally cycled between 293K and Tmax = 573K, 673K and 773K. Composites thermally cycled at Tmax = 573K and 673K were contracted by 1,000 cycles, but after that expanded with increasing the number of thermal cycling. Composites thermally cycled at Tmax = 773K uniformly expanded with increasing the number of thermal cycling. The thermal strain on thermal cycling of composites reinforced with ABp is less than that of composites reinforced with aluminum borate whiskers. The HR-TEM observation revealed that an ABp was composed from super fine particles. The finite element method analysis assumed the plastic deformation was caused in the composites heated from 273K to 573K.
