  1. The microstructure, structure, composition, phase of joint region, and the microstructure and composition of fracture have been analyzed using the equipment of metallurgical microscope, sem, eds, xrd and binary eutectic phase diagram for the al - cu system and diffusion theory

    利用金相顯微鏡、掃描電鏡、能譜儀、 x射線衍射分析儀，結合al - cu二元合金相圖及擴散理論，分析了接頭區域的形貌、組織、成分、相組成，以及斷口形貌、成分。
  2. The growth morphology of cu - cr eutectic are studied. during the process of eutectic growth, ( + ) growth is clinging to a phase. because cu - cr eutectic have very good coupling relation, the configuration of eutectic holds crystallography structure, and the influence of the direction of heat flow is not distinct

    2揭示了cu - cr共晶的生長形態，發現其在共晶生長過程中，共晶體（ + ）依附在相上生長； cu - cr因有較好的共格關系，其共晶形貌按照其結晶結構學特點生長，定向凝固下熱流的方向影響不顯著。
  3. The effect of solidification rate on the solidified structure, cooperation growth zone and microstructures such as tac rods volume fraction, tac rods average spacing, tac average transverse area and y phase in this eutectic composite were systematically investigated with lmc. the relationship between solidification processing controlling and solidification microstructure was established

    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，考察試樣的界面形態、組織特徵以及共晶形貌等多方面的凝固特性，建立了凝固過程式控制制與凝固組織的對應關系。
  4. That the alloying element mn and ti substitutes the atom of fe in the rich iron - phase ( al, si, fe ) and resumes the part of the element si in primary phase refines the second phase. at the same time, the volume percentage of second phase is increased. at the course of solidification, the alternating current field changes obviously the microstructure morphology of the al - 20si - 5fe - x alloy and the number of particle eutectic structure is increased

    合金元素mn 、 ti通過占據富鐵相（ al ， si ， fe ）中鐵原子的晶格位置，同時消耗部分初生相中的si元素，形成四元富鐵相（ al ， si ， fe ， mn ） ，細化了合金中的第二相，同時提高第二相體積百分數。
  5. The maximal power outputs of 37. 0 mw / cm2 and 30. 0 mw / cm2 for the p - and n - type laminated materials respectively at the temperature difference 490 have been experimentally obtained, which are about 2. 5 and 3. 0 times those of - fesi2. chemical analyses show that the interface failure between the bridge alloy and the semiconductor bi2te3 results mainly from the eutectic mixtures with low melting point and brittle compounds formed during welding and long time annealing at 190. it is found that the electrical properties of a laminated structure are mainly controlled by the wettability of the bridge alloy on the semiconductor surface

    發現： 1 ）疊層材料具有明顯優于均質材料的熱電性能，在490溫差下， p -型和n -型疊層材料的最大輸出功率分別達到37 . 0和30 . 0 （ mw / cm ~ 2 ） ，是同類型均質- fesi _ 2的2 . 5和3倍； 2 ）在焊接過程和190長時間退火處理過程中，焊接過渡層合金和基體半導體（特別是bi _ 2te _ 3 ）之間存在明顯的元素相互擴散，從而在過渡層中形成一些低熔點共晶體和脆性化合物，這是導致疊層材料破壞的主要原因； 3 ）焊接過渡層合金與半導體基體之間的潤濕性是影響界面層電性能的主要因素。
  6. Influenced by the alternating current field, except that a little of eutectic iron - phase still is the acicular structure, the most of eutectic iron - phase of the al - 20si - 5fe - mn alloy is refined into tiny particles which is segregated

    Al - 20si - 5fe - xti合金通過交流電場作用，共晶組織全部呈細小的顆粒狀均勻分佈於- al基體上。
