摘要：

The deformation mechanism of Hadfield steel depends on the crystallographic orientation and the sign of the load. Deformation occurs by slip and twinning, which affects the properties during nanoindentation. The paper studies the orientation dependence of the nanoindentation parameters of Hadfield steel. It is found that the nanohardness is the higher the larger the number of equally loaded slip systems. The difference in the elastic modulus depending on the crystallographic orientation can reach 50%. The highest hardness and elastic modulus are determined for the indented {001} plane. Compression deformation in this crystallographic direction gives rise to active twinning in Hadfield steel.
