The compression deformation behavior of single-crystal micropillars of L12–Co3(Al,W) has been investigated at room temperature as a function of pillar size and crystal orientation. The critical resolved shear stress (CRSS) obeys an inverse power-law scaling against pillar size and is independent of...
