Fig. 2

a Compressive engineering stress-strain curves of the pillar samples tested with identical conditions at room temperature. The height/diameter ratio is 2, and the diameter is 500 nm. The inset is a SEM image of a nanopillar before compression. b Engineering stress-displacement curve, derived from an in-situ TEM cyclic loading-unloading compression on a crystal-glass nanolaminated alloy nanopillar. The true stress was calculated via instantaneous load divided by instantaneous area of the nanopillar, where the instantaneous area was measured from the in-situ TEM compression video. The inset is a snapshot image of the in-situ TEM compression video before 1st loading, where the scale bar on the bottom left denotes 250 nm.
