Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Metallurgical Engineering Summary: The goal of this thesis is to improving the microstructure and the mechanical properties of AM60 magnesium alloy by using two different processes: RE and/or Si are used as a melt treated additions,The casting process are carried out under control atmosphere of Sf6/Ar at 750o C, after which the ingots are homogenized at 380o C for 2 hours, and then all samples are subjected to TMT(five paths of hot rolling each path10% reduction at 430oC and directly water quenched). Samples are investigated using XRF, optical electron microscope, SEM & EDX, mechanical tests, hardness and tensile strength.The results showed that the highest grain refining is obtained after TMT of alloy containing RE and Si (13æm), also has highest hardness 79 HV, maximum tensile strength 337 MPa, greater yield strength 207 MPa, and best elongation 17%

The goal of this thesis is to improving the microstructure and the mechanical properties of AM60 magnesium alloy by using two different processes: RE and/or Si are used as a melt treated additions,The casting process are carried out under control atmosphere of Sf6/Ar at 750o C, after which the ingots are homogenized at 380o C for 2 hours, and then all samples are subjected to TMT(five paths of hot rolling each path10% reduction at 430oC and directly water quenched).
