  4. In this work, using elemental powders as starting reactant materials several carbide powders such as wc, sic, tic, zrc and corresponding alloys had been fabricated by ball - milling technique. x - ray diffraction ( xrd ), scanning electron microscopy ( sem ), transmission electron microscopy ( tem ) and other measurement techniques had been used to monitor the structural changes of powders after some ball milling time and the properties of the cemented tungsten carbides. and the mechanism for the formation of matal carbides by ma has also been discussed

    本文主要對機械合金化（ ma ）技術在碳化物制備中的應用進行了研究，利用高能球磨，以元素粉末為原料，制備出wc 、 sic 、 tic 、 zrc的粉體以及wc基硬質復合材料，並利用x射線衍射、掃描電鏡、透射電鏡等方法分析和研究了球磨過程粉體的變化以及燒結后硬質合金的性能，對機械合金化制備碳化物的有關機理進行了研究和探索。
  5. 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。
  6. Powdered metals alloying of metals involves melting the main ingredients together so that on cooling, the metal alloy is generally a nonporous solid

    粉末合金金屬是通過熔化主要金屬元素並結合在一起，然後使之冷卻而形成的。
  7. In this dissertation, the magnets were prepared by powder metallurgy. powders of ag were added during ball milling, and powders of al and ti were added separately and jointly during ball milling, while al and ti were jointly added during melting. the samples were sintered for 0. 5h at 1090

    本文採用粉末冶金方法制備燒結磁體，在制粉階段添加ag元素，並單獨和復合添加ti 、 al元素，在熔煉階段復合添加ti 、 al元素，坯體在1090燒結0 . 5h 。
