| 3. | 3 . the uneven distortion of contact finger is due to the uneven distribution of cr along circle of the contact during infiltration
( 3 )触指不均匀变形是由于在熔渗过程中cr元素偏析上浮，在圆周方向分布不均而致。 |
| 4. | W - cu composites are usually fabricated by infiltration - sintering porous tungsten compacts with molten copper or by liquid - phase sintering w - cu powder compacts
W - cu复合材料通常采用粉末冶金熔渗烧结或液相烧结法制取。 |
| 5. | It is reverse for the composites having low cr content . 3 . hardness of the composites decreased and electrical conductivity increased with decrease of cr content while infiltration temperature is same
在同一温度进行熔渗时，随着cr含量的降低，材料的硬度降低，电导率升高：加入fe后材料的硬度显著升高，电导率则降低。 |
| 6. | In addition , another experiment was carried out that the powdered aluminum and copper was pressed in one die with a same pressure and infiltrated them after that with a hardness test of the aluminized copper sample and the obvertion of its microstructure
本文还试验了通过铜粉与铝粉在同一模具内，同一压力下压制后熔渗的实验，并对渗后的试样进行了硬度测试和微观组织的观察。 |
| 7. | The steel driver cab serving in ha - trains was adopted as the design prototype ; an integral composite driver cab ( icdc ) was investigated and designed in this paper based on the excellent characteristic of the composite materials and the resin film infusion ( rfi ) process technology
本文以正在服役的钢制哈车(出口哈萨克斯坦)机车司机室为设计原型,在充分发挥复合材料优异的承载性能基础上,结合树脂膜熔渗工艺( rfi )特点研究设计复合材料整体司机室。 |
| 8. | Cr particles were enclosed by cr - w solid solution alloy after cr powder and w powder were sintered if the grain size of cr powder is larger than w powder . around cr particles more cr - w solute was formed with prolonging sintering time . during infiltration process , cr was dissolved and moved into the pores in w skeleton by cu liquids and made w skeleton become w - cr skeleton
粒度较大的cr粉和粒度较小的w粉混合烧结后，形成crw固溶体合金包围cr块的组织形貌，烧结时间越长， cr块周围形成的crw固溶体越多；熔渗过程中， cr被cu液溶解并转移到w骨架之间的孔隙中， w骨架则转变为cr - w骨架。 |
| 9. | 1 . the splitting from the binding interface of cuw / crcu roots from the rich cr and the oxidation of the binding interface , which leads to the higher thermal resistance in binding interface than normal , and the thermal stress enhanced . the extruded cu is suggested to instead of casting cu
( 1 )断裂是由于原材料铸态的crcu中c :质点大于熔渗的孔隙而沉积在界面上，同时在有氧源存在的条件下，结合面氧化，致使结合面结合不好，界面热阻升高， cuw与crcu部分的膨胀不同，应力集中，燃弧后断裂。 |
| 10. | The experiment result showed that , in the infiltration melting the evaporation speed of si is more rapid than mo . the melting which enrich the mo reacted with the sic body and there existed mo5si3c . the content of mosi2 can be controled by adjusting the contend of c in the perform ; the content of c is more high the pore volume in composite is more high
研究发现，由于熔渗体中si的挥发速度快造成材料物相组成变化，熔渗体与sic坯体反应析出mo _ 5si _ 3c 、 mo _ 5si _ 3相阻塞坯体毛细管，使烧结体中产生气孔。 |
