Microstructure and Properties of a Low-Density Steel with High Strength of 1350 MPa

A low-density steel Fe-20Mn-10Al-1.0C with high strength of 1350 MPa was developed. The mechanical properties and microstructure evolutions of Fe-20Mn-10Al-1.0C steel under various heat treatment conditions were investigated by means of optical microscopy, X-ray diffraction and high resolution elect...
