DOI: 10.1016/j.ijplas.2018.07.012
Abstract: Abstract Lath martensitic steels possess excellent mechanical properties because of the special microstructure, i.e. laths, blocks and packets with particular crystallography in a prior austenite grain. To theoretically analyze the mechanical behavior of lath martensitic… read more here.
