The enthalpies of mixing in binary liquid alloys of manganese with the lanthanides (Nd, Gd, Tb, Dy, Tm and Lu) were determined over a wide range of composition by isoperibolic calorimetry. The heats of mixing in the systems were found to change gradually across the lanthanides row from the Mn–Nd system (ΔHmin = – 0.40 ± 0.26 kJ mol− 1 at xNd = 0.14; ΔHmax = 1.99 ± 0.65 kJ mol− 1 at xNd = 0.60; T = 1 600 K) to the Mn–Lu system (ΔHmin = – 6.76 ± 0.93 kJ mol− 1 at xLu = 0.40; T = 1 700 K)
The enthalpies of mixing in binary liquid alloys of iron with the lanthanides (Pr, Nd, Gd, Tb, Dy and Lu) were determined at 1550–1950 K by means of isoperibolic calorimetry. They show exothermic effects (in the Fe–Pr system partially endothermic) which increase across the lanthanides row from the Fe–Pr system (ΔHmin = −0.35 ± 0.10 kJ · mol−1 at xPr = 0.22; ΔHmax = 0.75 ± 0.24 kJ · mol−1 at xPr = 0.76; T = 1829 K) to the Fe–Lu system (ΔHmin = −11.58 ± 0.50 kJ · mol−1 at xLu = 0.35; T = 1950 K).
The enthalpy of mixing for liquid binary alloys of lanthanum with 3d-transition metals (Sc, Ti, V, Cr, and Fe) is determined by a calorimetric method within the field of compositions rich in lanthanum. Data for the partial enthalpy of mixing in the La − 3d-metal system with infinite dilution demonstrates a complex relationship of a change in it in the series of 3d-metals connected with gradual filling of the 3d-zone due to alloy formation with lanthanum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
