  1. The experimental data has been used to validate pdm and low temperature sintering mechanics. the advantage and disadvantage of pdm have been discussed also. for the first time, the pdm is used to study the low temperature sintering mechanics of uo _ 2, and the research results indicate : 1

    3 、基於燒結頸長大速率與緻密化動力學方程得出，影響二氧化鈾低溫燒結的因素有原始粉末粒徑、粉末堆積方式、坯塊原始密度、燒結溫度、燒結時間、燒結氣氛等;粉末壓坯一定時，燒結溫度、燒結時間和燒結氣氛就成為控制低溫燒結的關鍵因素。
  2. Microstructure of the composite layer was analyzed with help of optical microscope, scanning electronic microscope ( sem ), electronic probe microanalysis ( epma ) and x - ray diffraction ( xrd ). the compacting of the billet and the forming mechanism of the carbide reinforcement were studied based on thermodynamics and kinetics of reaction, sintering theory and the result of dta. at the same time, the wear - resistance of the composite layer was studied under condition of dry sliding friction

    利用光學顯微鏡、掃描電子顯微鏡、電子探針以及x -射線衍射儀，分析了表面復合層的基體組織結構；運用反應熱力學、動力學、粉末燒結理論和燃燒合成理論，結合差熱分析結果，探討了表面復合層壓坯的燒結緻密化原理和碳化物增強相的形成機理；利用坯塊在真空燒結爐不同溫度下的燒結出來的顯微組織分析，模擬出坯塊的燒結過程中的化學反應過程。
  3. Pdm is utilized to forecast the non - crystal phenomena in the sintering process and study the effect of non - crystal on the process of sintering

    因此採用超化學計量uo _ （ 2 + x ）坯塊是實現低溫燒結的必要條件。
  4. The speed became fast at the temperature 1050. the reaction could carry completely when billets was kept in vacuum tube for 3 hours " at 1050 temperature, under the striking of great quantity of heat when the molten iron poured into the mold, the reaction was blazed rapidly and continued at a high speed. the diffusible speed of v and c was very fast because the billet was heated over 1300 in a moment, so the reaction ca n complete in a few minutes

    （ 5 ）碳化反應v + c vc在900左右開始發生，此時是固相反應，反應速度較慢，反應不能進行完全，隨溫度升高，該碳化反應的速度加快，在1050保溫3小時可以進行完全，在鑄造燒結時在過熱鐵水的巨大熱流密度沖擊下， v + c vc立即被激發，並以很快的速度進行，由於坯塊被加熱到1300以上，此時c和v擴散速度很快，因此鑄造澆注后的幾四川大學碩士學位論文分鐘內反應可以進行完全。
