B. Gardiola et al., Determination and prediction of the inherited ferrite texture in a HSLA steel produced by compact strip production, MAT SCI E A, 303(1-2), 2001, pp. 60-69
The ferrite and residual austenite textures were measured in a microalloyed
(high strength low alloy, HSLA) steel produced by compact strip production
, a process for the production of hot strips from a continuously cast slab
using direct charging. The conditions of the thermomechanical rolling influ
ence the texture and microstructure of austenite and thus modify the mechan
ical behaviour of the final products, obtained after a gamma to alpha phase
transformation. The ferrite and residual austenite phases show strong text
ure gradients in the thickness of the sheet. Simulations of the thermomecha
nical rolling using the Taylor model allowed us to relate qualitatively the
main trends of the surface and mid-thickness textures of the austenite to
the process. By modelling the phase transformation, the surface and mid-thi
ckness inherited ferritic textures have been computed, without variant sele
ction, from the residual austenite texture. These simulated textures are co
mpared with the experimental ones and the texture inheritances are discusse
