(a) SEM image of [525] oriented B2 micro- pillars (inset figure shows IPF + IQ map and a pole figure with a point in center (circled in red) confirms [525] orientation of the B2 pillar); (b) SEM image of [203] oriented L1₂ micro-pillars (inset figure shows IPF + IQ map and a pole figure with a point in center (circled in red) confirms [203] orientation of the L1₂ pillar); (c) compressive engineering stress-strain curves (dotted lines in black indicate 0.2% offset) of the [525] oriented B2 micro-pillars with the inset showing yield strength values for three representative micro-pillars; (d) compression engineering stress-strain curves (dotted lines in black indicate 0.2% offset) of the [203] oriented L1₂ micro-pillars with the inset showing yield strength values for three representative pillars; (e) compressive engineering stress-strain curves of a micro-pillar containing both B2 and L1₂ phases showing double yielding phenomenon.
