1) ageing resistance
钇稀土
1.
, the microstructures and the ageing resistance of zinc alloy ZA-27 with different contents of yttrium were studied.
当钇稀土含量较高时,由于在晶界与晶内均有大块钇锌相生成,破坏了合金晶界的致密度,并增加了相界面,从而使合金的抗腐蚀性能有所下降。
2) rare earths of low yttrium
低钇稀土
1.
The ternary light rare earths (Pr,Nd,Sm),the ternary heavy rare earths (Dy,Ho,Er)and the rare earths of low yttrium including fifteen kinds of displacer C_(EDTA)=0.
通过对三元轻稀土(Pr、Nd、Sm)和重稀土(Dy、Ho、Er)以及含有15个稀土元素的低钇稀土的分离,表明在C_(EDTA=0。
