EXPERIMENTAL INVESTIGATION AND SIMULATION OF THE TEXTURE EVOLUTION DURING ROLLING DEFORMATION OF AN INTERMETALLIC FE-28 AT.PERCENT AL-2 AT.PERCENT CR POLYCRYSTAL AT ELEVATED-TEMPERATURES

The development of crystallographic texture during warm rolling of B2 ordered polycrystalline Fe-28 at.% Al-2 at.% Cr aggregates has been ex amined. The evolution of rolling texture has been simulated by means o f Taylor-type 'relaxed-constraints' models. Good correspondence of mod elled and experimentally detected rolling textures was found for simul ations based on activation of {110}[111] and {112}[111] glide systems. According to these simulations it is not likely that considerable amo unts of slip on {001}[100], {011}[100] or {123}[111] slip systems cont ribute to plastic deformation of Fe-28 at.% Al-2 at.% Cr compounds dur ing rolling at elevated temperatures.
