SEM images of a typical Au-BMG micropillar (a) before and (b) after compression.
True stress-strain curves from microcompression of Au-BMG pillars at high temperatures: (a) P-1 (constant strain rate: ), and (b) P-2 (strain rate change: ), P-3 , P-4 , and P-5 .
Stress vs strain rate for Au-BMG pillars at different temperatures with curves fitted by Eq. (1). The slope is for eye guidance of Newtonian flow.
Pillar sample height change and thermal drift in microcompression tests.
Fitted parameters in Eq. (1) from the results of micro-compression of Au-BMG pillars.
