Abstract:

Differential scanning calorimetry DSC was conducted using a monolithic 6061 aluminum material and two 6061 aluminum matrix composite materials. The composite materials were reinforced with 10 volume percent and 15 volume percent alumina particles. Electrical resistivity and hardness measurements during isothermal aging treatments were also conducted. The effects of prior aging and alumina particle additions on the growth kinetics and the thermal stability of the metastable phases in each material were studied. The results were used to characterize the effect of reinforcement on the aging kinetics of composite materials.
