Abstract
The deformation behaviour of near alpha titanium alloy Timetal 834 was investigated by analysing Considére criterion in temperature range between 300 and 500°C at an interval of 25°C. In the dynamic strain aging (DSA) regime (400–475°C) studied in this material, Considére criterion was satisfied partially at peak DSA temperature (450°C). This was attributed to maximum DSA effect at 450°C which eventually resulted in specimen fracture at low ductility levels. Strain hardening exponent (n) values was determined using Ludwik plot, Considére criterion and obtained experimentally from uniform strain. The n values obtained from Ludwik plot and Considére criterion were greater than the uniform strain in DSA regime studied.
