<p>A method for degassing and solidifying aluminum alloy powder is mprovided that can eliminate drawbacks inherent in a conventional method by making induction heating available for degassing means during processes of forming and solidifying aluminum powder and aluminum alloy powder. The method comprises the steps of pre-forming aluminum powder, aluminum alloy powder, aluminum composite alloy powder or powder mixtures of these powders and non-ferrous metal particles to a specific resistance of 0.2 Φ cm or lower, removing heat decomposable evaporation components by directly induction heating the pre-formed body in the normal pressure atmosphere so as to raise the temperature thereof to 400 °C to 600 °C while maintaining a temperature rise gradient over 300 °C at 0.4 °C/scm or higher, and reducing the hydrogen content to less than 10 ppm.</p> |
