On possibility of process combination of htge and sphts

The possibility of combining the processes of high-temperature gas extrusion (HTGE) created in the IFVD RAS and self-propagating high-temperature synthesis (SPHTS) created in the ISM RAS was experimentally confirmed with an example of composite blanks containing a compacted powder mixture of dispersed nickel and aluminum in a steel shell during deformation by gas extrusion with a degree of 75% inert gas under pressure from 200 to 450 MPa at a temperature from 600 °C to 800 °C, extrusion speed from 1 to 10 mm per second. As a result of the processing by the combined action of HTGE and SPHTS, an intermetallic nickel-aluminum monolith with hardness up to 60 units by HRc was obtained.
