Abstract

The current status and prospects of hot forging of porous preforms (HFPP) for producing structural engineering parts are discussed. The causes of the reduced scope of research in the field of HFPP in 1990-2010, as well as the advantages and disadvantages of the process, are analyzed. The method makes it possible to produce high-dense materials for heavy-duty applications. The complexity of the parts" shape is limited by the performances of the hot-forging equipment in use. The need for substantial capital expenditures in basic and auxiliary equipment is the critical area of the process, so HFPP would be appropriate for mass production of parts. Promising areas for the development of HFPP are identified.
