Abstract
A novel medium heavy alloy (MHA) a composition designed and processed such that the MHA has properties comprising a tensile strength of about 1527 MPa, a proof strength of about 1337 MPa, and an impact toughness of about 180 J, when the MHA is forged, and the tensile strength of about 1746 MPa, the proof strength of about 1571 MPa, and the impact toughness of about 55 J, when the MHA is agedly treated. The superior strength-toughness is attributed to the face-centered cubic matrix and/or the nano-sized secondary phases. The superior dynamic performance is attributed to the widening of adiabatic shear bands.
