چکیده انگلیسی
In addition, the limiting partial molar enthalpy of Co in Sn was investigated by small additions of Co to liquid Sn at temperatures (673 to 1773)Â K. The integral and partial molar enthalpies of the Co-Sn system generally show an exothermic mixing behavior. Significant temperature dependence was detected for the enthalpies of mixing. The minimum integral enthalpy values vary with rising temperature from approx. â7820Â J/mol at TÂ =Â 1173Â K to â1350Â J/mol at TÂ =Â 1773Â K; the position of the minimum is between (59 and 61)Â at.% Co. The results are discussed and compared with literature data available for this system. X-ray studies and scanning electron microscopy of selected alloys obtained from the calorimetric measurements were carried out in order to check the completeness of the solution process.
