5.Thermodynamic Investigation on the Liquid Sintering of the Refractory Mo Alloys

Abstract:Using CALPHAD method,the phase diagrams of the Cu-Ni,Cu-Mo and Mo-Ni binary systems were calculated by employing the thermodynamic database in literature.Through extrapolation from the relative binary systems,the isothermal section of Mo-Ni-Cu ternary system at 1273K was calculated.It is found that there is a narrow liquid phase area at the Mo-rich side,which demonstrates the possibility of liquid phase sintering at 1273K with some amount of addition of Cu and Ni.Furthermore,necessary experiment was carried out to cinfirm the calculation results.
Key words:CALPHAD technology,thermodynamic,extrapolation,liquid phase sintering,Mo-Ni-Cu ternary system

鉬合金耐火材料液相燒結性能熱力學研究
摘要：利用文獻已有的體系熱力學數據，采用計算材料科學的方法計算了Cu-Ni、Cu-Mo、Ni-Mo3個二元體系相圖，并熱力學外退了Mo-Ni-Cu三元體系1273K等溫截面圖，發現在富Mo角存在一個狹小的液相區，表明在1273K的溫度小已通過添加適量的銅鎳固溶液可改善Mo合金的液相燒結性能，并實驗驗證了計算結果。
關鍵詞：CALPHAD計算、熱力學外推、液相燒結、Mo-Ni-Cu三元體系
