eutectic alloy 低共熔合金。

eutectic point

In experiment , the dsc technique was used to analyze the effect of electric fields on the precipitate kinetic of al - li alloy solutionized with electric fields . the energy spectrum , tem and sem techniques are employed to investigate the elements solution , precipitates , fracture character , conductivity and vickers hardness . also , the solidification of al - cu eutectic alloy was conducted with the influence of electric fields 在實驗上,利用dsc熱分析技術,分析了電場作用對al - li合金相析出動力學的影響;采用能譜成份檢測,透射電鏡和掃描電鏡等多種微觀檢測手段,對鋁合金的析出相,斷裂特征、合金電導率和維氏硬度等性能在電場作用下的變化進行了系統的研究,并觀察了al - cu共晶合金在電場作用下的凝固組織。

The containerless rapid solidification of al - 32 . 7wt % cu eutectic alloy in drop tube is investigated . the “ lamellar eutectic - anomalous eutectic “ microstructural morphology transition occurs with the decrease of droplet size 采用落管無容器處理技術研究了al - 32 . 7wt cu二元共晶合金在深過冷條件下的快速凝固規律。
