  1. Therefore, in this paper, two directional solidification methods, czochralski method and electron - beam floating zone melting method, were used to obtain such material. the directional solidifition microstructures of si - tasi2 system was performed using neophot - 1, amray - 100b sem and jem - 2000cx tem analysis technique

    本文採用切克拉斯基法( cz法)和電子束區熔法( ebfzm )兩種定向凝固方法制備該共晶自生復合材料;藉助金相技術、電鏡技術、圖象處理技術等多種分析測試手段,考察了si - tasi _ 2共晶定向凝固組織和及其相應的工藝規范。
  2. The results indicate that arc melting is a good method to produce nb - si system intermetallics due to its simpler technics, lower cost and compact products. however, powder metallurgy is found to be not suitable to produce the nb - si system intermetallics due to its coarse and loose products resulting from the poor molding property of nb and si mixed powders. optical floating zone technology, which is used to fabricate nb - si intermetallic composites for the first time, is also found to be a good way to produce nb - si system intermetallics because of its compact products and good property despite of its relatively high cost

    結果表明,電弧熔煉方法制備得到的nb - si系金屬間化合物比較緻密,且制備工藝簡單,經濟實用,是一種合適的nb - si系金屬間化合物制備方法;由於nb 、 si元素粉末的成型性很差,用粉末冶金方法(熱壓燒結和冷等靜壓)制備的nb - si系金屬間化合物表面粗糙、緻密度低,且成本較高,不宜用於制備nb - si系金屬間化合物;首次用光學懸浮單晶生長技術制備的nb - si系金屬間化合物復合材料緻密度很高,盡管成本稍高,但由於性能最佳,也是一種合適的nb - si系金屬間化合物制備方法。
