Crystal structure and electrical resistance of Ni-W alloys
The purpose of the paper is to establish the correlation between chemical composition, phase content and magnetic ordering of Ni₍₁₋x₎Wx alloys and behavior of their electronic properties in a wide range of temperatures. Alloys Ni₍₁₋x₎Wx of different composition (0 < x < 0.5) are synthesized. I...

The purpose of the paper is to establish the correlation between chemical composition, phase content and magnetic ordering of Ni₍₁₋x₎Wx alloys and behavior of their electronic properties in a wide range of temperatures. Alloys Ni₍₁₋x₎Wx of different composition (0 < x < 0.5) are synthesized. It is studied the crystal structure and the nature of the temperature dependence of electrical resistivity. It is shown, that in the range of concentrations of tungsten 0 < x < ~0.15 there is only face centered cubic (FCC) lattice, whereas, at the higher values of x, the Ni-W alloy is two-phase system consisting of the face centered and body centered cubic (BCC) crystal structures.
