Abstract

Tension-tension tests on turned, electro-chemical machined (ECM) and electro-discharge textured (EDT) specimens made from Ti-45Al-2Nb-2Mn+0.8 vol% TiB2 alloy, showed the turned specimens to have a higher fatigue strength similar to 475 MPa. It is likely that this was due to the presence of highly compressive surface residual stresses caused by the turning operation. (C) 2001 Elsevier Science Ltd. All rights reserved.
