Popis:	The 970-K phase relations in the Nb-Cr-Sb and Nb-Mn-Sb systems have been studied by X-ray diffraction. The systems contain no ternary compounds. There are substitutional solid solutions based on binary antimonides. The Nb5Sb4-based solid solution (Ti5Te4 structure) extends to the composition Nb4.1Mn0.9Sb4; the Nb3Sb-based solid-solution series (Cr3Si structure) is bounded by the compositions Nb2.6Cr0.4Sb and Nb2.4Mn0.6Sb; the Cr1.04 − xSb0.96 + x-based solution with x = 0.08 (NiAs structure) exists between the compositions Cr0.94Nb0.10Sb0.96 and Cr0.70Nb0.30Sb1.00; and the Mn1.00 + xSb1.00 − x-based solution with x = 0.1 extends to the composition Mn0.9Nb0.2Sb0.9. In addition, there is an interstitial solid solution (Ni2In structure), which extends to MnNb0.25Sb. The 970-K isothermal sections of the Nb-Cr-Sb and Nb-Mn-Sb phase diagrams are mapped out in the region 0–80 at % Sb.
