Effect of Rare Earth Ce on Microstructure and Mechanical Properties of A356 Aluminum Alloy AITranslate
Abstract AITranslate
The effect of rare earth Ce on microstructure and mechanical properties of A356 alloy was studied by using OM, SEM, EDS, XRD and universal electronic tensile testing machine. The results indicate that rare earth Ce is an excellent modifier for A356 alloy. Ce is helpful not only for refining the grains of primary α-Al phase,but also for forming small,round and uniform eutectic Si. Rare earth Ce in A356 alloy exists mainly in the form of rare earth intermetallic compound Al11Ce3. When 0.04% Ce is added into A356 alloy,its tensile strength,yield strength and elongation respectively reach 307.5 MPa,239 MPa and 7.72%, increased by 7.89% ,24.48% and 108.09% compared with the alloy without Ce.
