The tensile properties of a particulate reinforced al alloy in the temperature range -196–300 °c

The tensile properties of a particulate reinforced Al- Si-Mg alloy were determined in the temperature range — 196–300 °C. Microstructural coarsening of a peak aged (T61) material occurs at the higher temperatures (i.e. 200 and 300 °C), which, together with the test temperature, results in a considerable decrease in flow strength for both the composite and unreinforced alloy. However, the strengthening ratio (i.e. the ratio of composite to …
