Abstract
The present invention describes a process for the compaction and densification of materials using heat and high pressure in which pressure is applied isostatically to the workpiece to be compacted, heat is applied to the pressurized workpiece as rapidly as feasible, effecting thereby full compaction and densification. Heating is terminated and the workpiece cooled while the workpiece is still pressurized. This process effects hot-isostatic-processing of workpieces while reducing the time such workpieces spend at elevated temperatures. The resulting parts can have novel structures, properties or compositions not obtained with other processing procedures.
