Abstract

The creep behavior of AX44 (Mg-4Al-4Ca, wt%) and AXJ530 (Mg-5Al-3Ca-0.15Sr, wt%) was investigated in permanent mold cast alloys at stresses ranging from 60 to 90 MPa at 175°C. A strain mapping technique was used to investigate deformation, using a periodic array of micron-scale markers deposited on the specimen surface. By measuring changes in array spacing as a function of creep strain a two-dimensional strain field is calculated at the specimen surface. Strain distributions developed during creep were investigated with particular attention given to assessing the role of microstructure. Evidence for microstructure dependent strain localization was observed during creep.
