If the alloy is in itself sensitive to the oxygen, then not only in atomization time must take the measure, when melting should better also use the vacuum melting.
如果合金本身对氧非常敏感，则不仅在雾化时要采取措施，在熔化时最好也采用真空熔炼。

The alloy powder was produced by gas atomization. P/M material samples were made by pressing and sequent vacuum sintering.
