摘要： Some variations provide a metal-alloy biphasic system containing a first metal M1 and a second metal M2, wherein a second metal phase has a melting temperature lower than that of a first metal phase, and wherein the metal-alloy biphasic system has a hierarchical microstructure containing a second length scale that is at least one order of magnitude smaller than a first length scale. Some variations provide a metal-alloy biphasic system containing a first metal M1 and a second metal M2, wherein a second metal phase has a melting temperature lower than that of a first metal phase, and wherein the first metal phase forms a continuous network. Other variations provide a metal-alloy biphasic powder containing at least a first metal and a second metal, wherein the solubility of first metal in second metal is less than 5%. Methods of making and using the powders and biphasic system are disclosed.

摘要： A Ni—Ti-based alloy material includes a matrix phase consisting essentially of a Ni—Ti-based alloy and having a B2 type crystal structure. A nonmetallic inclusion is present in the matrix phase, in which 99% by mass or more of the nonmetallic inclusion is a TiC-based inclusion having a NaCl type crystal structure, the TiC-based inclusion has a lattice misfit (δ) in a range of 0.4238 or more and 0.4259 or less. The lattice misfit (δ) is represented by Expression δ=(a1−a2)/a2, where a1 is a lattice constant (Å) of the TiC-based inclusion and a2 is a lattice constant (Å) of the matrix phase.

摘要： 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.

摘要： 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.
