Lattice parameter and melting behavior of the ternary B2-phase in the Co-Ga-Ni system

Lattice parameter and DTA-measurements were performed in the range of the ternary B2-phase in the Co-Ga-Ni system which exhibits a continuous range of homogeneity. Lattice parameter values are reported for three ternary sections with constant ratios ofxCo/xNi=0.33, 1.00, and 3.00 as well as for the two limiting binaries. Solidus and liquidus temperatures are given for 0⩽xCo/xNi⩽3.00. The results of the DTA-measurements in the Ga-Ni binary system indicate a somewhat wider range of homogeneity on the gallium-rich side as compared with literature data.
