Abstract

The dependencies of indentation modulus and yielding behavior on the crystallographic orientation in a high Mn twinning induced plasticity (TWIP) steel were systematically investigated by spherical nanoindentation. A series of nanoindentation experiments revealed that the values of the plane-strain modulus and maximum shear stress at the pop-in increased with an order of (0. 0. 1), (1. 0. 1), and (1. 1. 1) grains. Mechanical twins were only observed in the indented (0. 0. 1) grains, as was expected from Schmid factor for twinning in fcc crystals.
