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(jié)性能熱力學(xué)研究
摘要：利用文獻(xiàn)已有的體系熱力學(xué)數(shù)據(jù)，采用計(jì)算材料科學(xué)的方法計(jì)算了Cu-Ni、Cu-Mo、Ni-Mo3個(gè)二元體系相圖，并熱力學(xué)外退了Mo-Ni-Cu三元體系1273K等溫截面圖，發(fā)現(xiàn)在富Mo角存在一個(gè)狹小的液相區(qū)，表明在1273K的溫度小已通過(guò)添加適量的銅鎳固溶液可改善Mo合金的液相燒結(jié)性能，并實(shí)驗(yàn)驗(yàn)證了計(jì)算結(jié)果。
