Recent studies on fatigue crack growth of an alpha 2 titanium aluminide,Ti-24A1-11Nb intermetallic at room temperature [1-3] indicate a strong dependence of fatigue crack growth rate on the stress ratio, R (ratio of minimum stress to maximum stress) . Figure shows the variation of da/dN with stress
Tension-tension tests on turned, electro-chemical machined (ECM) and electro-discharge textured (EDT) specimens made from Ti-45Al-2Nb-2Mn+0.8 vol% TiB 2 alloy, showed the turned specimens to have a higher fatigue strength เท475 MPa. It is likely that this was due to the presence of highly compressive
