Findings from Sharif University of Technology Has Provided New Data on Materials Science (Softening behaviour of alumina reinforced copper processed by equal channel angular pressing)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Materials Science have been published. According to news reporting from Tehran, Iran, by VerticalNews journalists, research stated, "In this present work, the softening behaviour of Cu-1.1 wt-% Al2O3 alloy containing nanometric alumina particles was investigated."

The news correspondents obtained a quote from the research from the Sharif University of Technology, "Single pass equal channel angular pressing was first applied on cylindrical specimens, and then, the deformed samples were subjected to annealing treatments in the temperature range of 700-1000 degrees C. Afterwards, finite element analysis, microstructural observations, Vickers hardness and shear punch testing were employed to study strain distribution as well as the recrystallisation behaviour of the examined alloy. It was found that the alloy is softened at 800 degrees C or above, which shows its high thermal stability."

According to the news reporters, the research concluded: "Furthermore, a very fine completely recrystallised microstructure was obtained via a continuous mechanism of recrystallisation at 1000 degrees C. The activation energy of recrystallisation was measured to be similar to 181 kJ mol(-1), which offers a high thermal stability in high temperature applications of this alloy."
