Conclusions
Optimum hot pressing conditions have been developed for Al-base metal-powder substances.
-
1.
Compacting temperature is 400–410°C, and pressure 7000–8000 kg/cm2. Compacting time depends on the size of the article to be compacted, and is of the order of seconds.
-
2.
Metal dies may be used without gas-shielding, for the hot pressing operation.
