| Abstract Scope |
Wrought magnesium alloy AZ31 with a thick section of 20 mm was prepared by squeeze casting (SC) and permanent steel mold casting (PSMC). The yield strength (YS), ultimate yield strength (UTS), elongation (ef), and strain hardening rate of the cast AZ31 specimens were evaluated by tensile testing. The measured engineering stress versus strain curves showed that the SC AZ31 alloy exhibited 62 MPa in YS, 194 MPa in UTS and 13.8% in ef, while the YS, UTS and ef of the PSMC AZ31 specimen were only 58 MPa, 173 MPa and 9.9%. The results of the tensile testing evidently showed that the YS, UTS and ef of the SC AZ31 alloy were 7%, 12% and 39% higher than those of the PSMC counterpart. The low porosity level of the SC AZ31 alloy should be somewhat responsible for its high mechanical properties. |
