Alloys of Pd—Ni—Cr system, where germanium is used as a depressant, are studied. As shown with the results obtained by high-temperature differential thermal analysis, the increase of germanium concentration leads to the decrease in solidus and liquidus temperatures of a base alloy. Using X-ray spectral microanalysis and metallographic examinations, the morphological features of structure formation of alloy at issue are revealed. As shown, at content of 1.15 and 2.66% wt. of germanium, the precipitation of single dispersed particles formed by two phases is observed along the boundaries of solid solution, but it is not possible to differentiate their chemical composition because of small size and insufficient locality of spectrometer measurements (1 m). With increase of germanium content in alloy up to 10.43% wt., number and size of the particles are increased. As determined, they consist of solid solution and Ge$_{y}$(Pd,Ni,Cr)$_{x}$ phase containing 23—24% wt. of germanium. As found, this is normal cellular eutectics with almost constant germanium content. With increase of germanium concentration in alloy, the significant increase of its content in solid solution is observed thus leading to the increase of microhardness and, hereby, to hardening.
