SINTERED TIAL INTERMETALLIC ALLOY PRODUCTION. PART 2. STUDY OF MOLDING AND SINTERING PROCESSES
https://doi.org/10.17073/0021-3438-2016-1-50-62
Abstract
An integrated process for producing electrodes of TiAl-based powder alloy is proposed with the following stages: powder alloy production by hydride-calcium recovery, powder treatment in a carbide ball mill with Y2O3 added as a structure modifier, workpiece hydrostatic molding and sintering. Experimental samples were used to study molding and sintering processes and examine alloy microstructure at all stages of the processing chain. An electrode for plasma centrifugal disintegration of granules was produced using this technology.
