Comparison of different routes for production of CP- Ti powder compacts used as preform for forging of Con-rod
conference contribution
posted on 2023-01-27, 04:07 authored by Rimma Lapovok, M Qiarr, C BottlesTo explore possible options for an economical route for the forging of a small con rod from CP Ti powder, two different methods for producing a forging preform were studied, namely direct compaction followed by sintering, and compaction via Equal Channel Angular Pressing (ECAP) with back pressure without sintering. It is shown that the use of ECAP with applied back pressure for compaction of powder leads to significantly reduced consolidation temperatures compared to those used in conventional practice. The ECAP compacts achieved 99. 9% theoretical density and strength of 180 MPa after processing at 30°C . The twofold gain in enhanced low temperature compaction and simultaneous grain refinement of CP Ti justifies the utilisation of ECAP with back pressure as a unique preform fabrication method for the production of small con rods by forging.
