The essential purpose of this research is to investigate the
influence of mechanical proporties in 6061 Al alloy and
6061 Al alloy matrix composites (AMCs) after thermal
cycling. The parameters of this research include the
particle size, volume fraction (0~30%) of reinforcement and
diferent thermal cycling and cooling rate.
From tensile test results, the strength droped sharply with
increasing thermal cycling and it led to a horizontal
value. The behavior is chiefly due to overaging. The
composite materials, following the thermal treatment, not
only underwent overaging of the matrix void coalesence, crack
formation and reinforcement debonding was also observed. The
overall effect of above phenomena resulted in a marked
decrease of tensile strength and yield strength. With
the increasing of reinforcement and decreasing of the particle
size, the ability to resist the influence of thermal cycling was
increasing. After thermal cycling, the elongation was
increasing, and the phenomenon of the dynamic strain aging
was also observed by faster cooling rates. From the
fracture surface observation, there is no evidence to prove that
thermal cycling caused the fracture of these materials.
