Change in thermochemical properties of aluminum nanopowders upon irradiation with electron beam and microwave

Abstract

In this work, aluminum nanopowder samples were irradiated with electron beam and microwave radiation of varying dose to ascertain their effect on thermophysical properties of metal powders. The results from the differential thermal analysis of the irradiated samples shows the highest value of thermal heat of oxidation (13678J/g) in the sample irradiated with microwave of (100J/50Hz ) with a corresponding highest peak temperature of oxidation (625⁰C). Based on the obtained experimental results, no correlation was observed between oxidation onset temperature and thermal effect of oxidation
