摘要：
The enthalpies of formation of the intermetallic compounds of the AI-Nb system were measured by direct reaction calorimetry at high temperatures. Results were compared with the available experimental values based on calorimetric and vapor pressure measurements and computed values based on the semiempirical model of Miedema. X-ray Powder Diffraction and Electron Microprobe Analysis techniques were used to verify the crystal structures and compositions of the phases under scrutiny. (C) 1998 Elsevier Science S.A.
