Relationship Between the Mechanical Properties of an Irradiated Metal Alloy and the Mechanical Properties of the Irradiated Elements of the Alloy

Abstract

In the article, we are trying to find a general law that describes the physical properties of a complex compound through the same physical properties of compound elements. For metal alloys operated under extreme conditions - neutron and proton irradiations and thermal heating, the mechanical properties of these alloys and their elements have been studied. It turned out that the ultimate tensile strength of tantalum alloys used in the design of space reactors can be expressed in terms of the weighted sum of the ultimate tensile strengths of its elements in the range of neutron doses: (0 - 0.96) displacement per atom (dpa) for Ta–10W alloy and (1.4 - 1.7) dpa for T–111 alloy with a neutron energy of more than 0.1 MeV. For tungsten binary alloys used in the design of fusion reactors, the Vickers hardness can also be expressed in terms of the weighted sum of the Vickers hardnesses of the alloy elements in the range of proton irradiation doses: (0 - 0.05) dpa for W-1%Re alloy, (0.05 - 0.2) dpa for W-3%Re alloy and (0.05 - 1) dpa for W-1%Ta with a proton energy of 1 MeV.

On Some Features of the Magnetic Properties of Nuclear and Other Materials

“…where [11], atomic numbers: Ni = 28, Zn = 30, Fe = 26, O = 8. The form q is chosen in such a way as to fulfill the requirements of clarity and simplicity [2][3][4][5]. The variable h, which depends on the lattice parameters, is associated with the most electronegative element, although it can be placed anywhere within parentheses.…”

“…For the resulting q, we calculated h (Table 3). It can be seen that for a fixed h for x = 0 and 0.2, the parameter q changes, although it is possible that both q and h are fixed in some ranges of external or internal parameters [2][3][4][5]. In this case, we multiply the weighted sum of the Curie temperatures by a variable depending on x and atomic numbers.…”
