Abstract

Strong and tough steel Ultrahard materials often do not have similarly impressive fracture toughness. Liu et al. discovered a processing route for medium manganese steel alloy in which ultrahigh strength accompanies high fracture toughness. The steel relies on both transformation-induced plasticity and delamination toughening to boost the fracture properties. The steel is composed of less expensive elements, making it a potentially inexpensive material attractive for structural applications. Science , this issue p. 1347
