  1. Test method for density determination for powder metallurgy materials containing less than two percent porosity

    含低於2 %率的冶金材料密測定的試驗方法
  2. Zny, ni ( 1 - y ) fe2o4 and cobalt substituted ni - zn soft ferrite powders of zn0. 4ni ( 0. 6 - a ) coa fe2o4 are synthesized by shs. the shs powders and cycle samples are annealing in 1100 for 2h. their magnetic, and micro structural properties are studied using xrd, vsm and sem techniques. the studies reveal that the value of hc mr and ms of the powder of zn yni ( 1 - y ) fe2o4 are maximal when the value of y is 0. 4

    研究發現:隨著zno含量( y值)的增加,產物的矯頑力( hc ) 、飽和磁矩( ms )以及剩餘磁矩( mr )先增大(在y = 0 . 4時取得最大值)然後再下降;磁環表面顆粒逐漸長大,率減少,密增加;磁環的bs與br先增大再減小,在y = 0 . 4時達到最大;磁環的矯頑力hc是遞減的。
  3. The results show that the optimal processing of 6061 aluminum foams which have structural uniformity and controlled porosity is the foaming temperature 620 - 690, heating rate 45 / min - 60 / min and heat preservation time is 12 - 18min. according to pore size tih2 content is chosen. when pore size is big, tih2 content is high and heat preservation time is short, vice versa

    研究結果表明,對于實驗採用的6061鋁合金材料來說,加熱發泡製備出結構均勻,率可控的泡沫鋁的最優條件是,加熱溫為620 - 690 ,保溫時間為12 - 18min ,加熱速率為45 - 60 min , tih _ 2含量可以根據所需徑的大小來確定。
