Abstract An investigation of the microstrain behavior of an age-hardenable, ferritic Fe-Si-Ti alloy has been made with the aim of characterizing the deformation processes in the early stages of yielding. In the solution-treated condition the value of the elastic limit obtained of 268 MN/m 2 after 1 pct prestrain is comparable with published values for Fe-Si alloys. In the aged conditions mechanical hysteresis was detected with zero prestrain and this is attributed to the restoring force on glide dislocations produced by antiphase boundaries in sheared particles. Both the elastic and anelastic limits are strongly dependent on the state of precipitation. In the prepeak and peak aged conditions the anelastic limit exhibits an extremely high dependence on strain. This is attributed to glide dislocations encountering areas of the particle array which are more difficult to penetrate and to the rapidly growing back stress due to dislocation accumulation in the well defined slip bands which are characteristic of deformation of this type of alloy.
