The influence of microchemistry on the recrystallization texture of cold-rolled Al-Mn-Fe-Si alloys
The recrystallization textures of a cold-rolled Al-Mn-Fe-Si model alloy with three different microchemistry states after non-isothermal annealing were studied. The microstructure and texture evolution have been characterized by EBSD. It is clearly demonstrated that the actual microchemistry state as determined by the homogenization procedure strongly influence the recrystallized grain size and ...
متن کاملATOMIC AND MAGNETIC SRO IN Fe-Mn-Si ALLOYS
Neutron diffuse scattering and saturation magnetization experiments have been made on single crystals specimens of Fe3-,MnCSi with c = 0.164 and 0.284 at room temperature. Atomic clustering of Mn atoms on the B sublattice has been revealed. A model of magnetic moment distribution around Mn impurities has been developed and fitted to the experimental magnetic diffuse cross sections. RRsults obta...
متن کاملEffect of Mn and Fe on the Formation of Fe- and Mn-Rich Intermetallics in Al–5Mg–Mn Alloys Solidified Under Near-Rapid Cooling
Mn was an important alloying element used in Al-Mg-Mn alloys. However, it had to be limited to a low level (<1.0 wt %) to avoid the formation of coarse intermetallics. In order to take full advantage of the benefits of Mn, research was carried out to investigate the possibility of increasing the content of Mn by studying the effect of cooling rate on the formation of Fe- and Mn-rich intermetall...
متن کاملEffect of heterogeneously distributed pre-existing dispersoids on the recrystallization behavior of a cold-rolled Al-Mn-Fe-Si alloy
a r t i c l e i n f o It is well known that strong concurrent precipitation, mainly located along grain/subgrain boundaries, results in a coarse and elongated grain structure, and unusual sharp P {011} b566N and/or M {113} b110N texture components during annealing of supersaturated AA3xxx-series alloys. In this study, a supersaturated as-cast Al–Mn– Fe–Si alloy was annealed at three temperature...
متن کاملtransformation in metastable Fe - Mn alloys
Metastable Fe-Mn alloys exhibit a non-thermoelastic martensitic transformation which is accompanied by a significant thermal effect (ca. 20 J/g). Among Fe-Mn alloys, the highest value of latent heat was registered in alloys with 17-18 wt. % Mn. In this work we investigate effects of carbon (up to 0.4 wt. %) and cold rolling (5-25% of thickness reduction) on the latent heat and the temperature h...
