Modeling of oxide breakup during equal channel angular pressing of reactively gas-atomized Al powders Academic Article uri icon

abstract

  • The influences of equal channel angular pressing (ECAP) conditions, such as number of passes, processing temperature, and tool angle, on oxide breakup of oxygen-containing gas-atomized Al powders were numerically studied. The modeling results show that the fragmented oxide's size decreases with an increase in number of passes and with a decrease in processing temperature and in tool angle. A few tens of passes are required to attain nanometric (1 to 10 nm) oxide particles. The theoretical calculations are generally consistent with the experimental data.
