Abstract
A medium heavy alloy (MHA) and a fabrication method thereof are disclosed. The MHA includes 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 method includes providing a composition designed according to design specifications of the MHA; forming a cast alloy from the composition by a metallurgy process; and forged the cast alloy at a first temperature to form the MHA having properties that are the design specifications.
