The Texture Behavior of Al-Mg-Sc Alloys
Three alloys of Al-Mg with and without scandium are cold worked at different percentage and then annealed. The texture behavior of the alloys is studied by X-ray diffraction technique. The X-ray diffraction analysis is done using a PHILIPS PW1830 diffractometer with Cu-Kα radiation. It is found that the addition of scandium in Al-6Mg alloy influences the development of texture. The cube texture...
متن کاملTHERMAL ANALYSIS AND KINETICS OF THE PRECIPITATION IN WROUGHT Al-Mg, Al-Mg-ScAND Al-Mg-Sc-Me (Me=Zr, Ti) ALLOYS
Precipitation behaviour of wrought Al-6Mg alloys with ternary scandium and quaternary zirconium and titanium has been studied. Hardness measurements and resistivity studies are employed to assess the precipitation behaviour of scandium doped Al-6Mg alloy without or with quaternary additions of zirconium and titanium. Further, the kinetics of precipitations are studied by differential scanning c...
متن کاملFRACTIONAL RECRYSTALLIZATION KINETICS IN DIRECTLY COLD ROLLED Al-Mg, Al-Mg-Sc AND Al-Mg-Sc-Zr ALLOY
The evaluation of texture as a function of recrystallization has been characterized for directly cold rolled Al-6Mg, Al-6Mg-0.4Sc and Al-6Mg-0.4Sc-0.2Zr alloys. Samples were annealed isothermally at 400 °C for 1 to 240 minutes to allow recrystallization. Recrystallization kinetics of the alloys is analyzed from the micro-hardness variation. Isothermally annealed samples of aluminum alloys were ...
متن کاملPRECIPITATION PROCESS OF Al-Sc ALLOYS
Precipitation process in an A1-0.25 wt.%Sc alloy aged at 573 K has been investigated by resistivity and hardness measurements, transmission electron microscopy, and atom-probe field ion microscopy. It was found that the equilibrium A13Sc phase particles precipitate homogeneously from the begining. The particles coarsen following the Lifschitz-Wagner rule after the completion of the nucleation-a...
متن کاملInfluence of thermomechanical processing on the grain size, texture and mechanical properties of Mg-Al alloys
The work carried out by the authors over the last decade on the processing, microstructural characterization and the mechanical behaviour of Mg alloys is reviewed. In particular, the potential for grain refinement and for the development of specific textures of large strain hot rolling (LSHR), equal channel angular pressing (ECAP) and accumulative roll bonding (ARB) is discussed. The recrystall...
