Abstract

To increase the strength of cast magnesium alloys operating at elevated temperatures, it is most important to increase their creep resistance. However, the influence of Mg-alloys die casting and permanent mold casting parameters on creep resistance has not been practically studied in the past. It is shown in this work that such casting parameters as metal injection rate into the die, die (mold) temperature and liquid metal temperature exert essential influence on creep resistance and other mechanical properties of the magnesium alloy AZ91D. It is established that in the case of permanent mold cast alloy, creep magnitude is defined by intermetallic β-phase inclusions, whereas in the case of die casting it is defined by the extent of micro- and macro-porosity development in the alloy.
