Grain size effect on behaviour and microstructure of a warm deformed Ti-IF steel
journal contribution
posted on 2003-06-15, 00:00 authored by A Oudin, Matthew BarnettMatthew Barnett, Peter HodgsonPeter HodgsonThe effect of grain size on the deformation behaviour in the fenite region of a Titanium stabilized Interstitial Free steel was investigated by hot torsion. The initial work hardening regime is followed by a softening regime where a broad peak stress develops. The peak stress and the stress at final strain were relatively insensitive to grain size. However, at low values of the Zener-Hollomon parameter, the strain to the peak stress was strongly dependent on the grain size. A series of microstructural parameters were examined to explain these observations.
