| Abstract Scope |
The energy saving is the most important goal in the automotive industry. Weight reduction of automobiles by adopting light weight materials is one of reliable methods to achieve the goal. Magnesium alloys have the potential to replace steel or aluminum for automotive materials. There were a lot of researches for studying the microstructures and mechanical properties of magnesium alloys. However, the effect of strain rate on the mechanical properties has not been studied thoroughly, especially in the condition of tension. In the present study, the effect of strain rate at the range of 10-4/s ~ 102/s on the tensile characteristics of AZ 31 magnesium alloy has been studied. The normal tension specimens were tested using a high rate hydraulic testing machine. Strength of AZ 31 magnesium alloy increases and ductility decreases with increasing the strain rate. Some stress-strain curves revealed the twinning phenomena according to their machining direction.-
