The results show that an alloy may be formed by ball-milling and amorphous character is enhanced with the increasing of the milling time.
结果发现，球磨可形成合金化，随球磨时间的增加，样品的非晶化逐渐加强。
As dielectric constant of samples decreases with increasing the ball milling time, impedance matching becomes better and the performances of microwave absorption are promoted.
由于随球磨时间增加样品介电常数下降，使得阻抗匹配变好，样品的微波吸收性能提升。
The simulation results show that, with increasing the milling time, the densification of powders becomes more and more difficult, and the needed extrusion pressure substantially rises.
分析结果表明， 随着球磨时间的延长， 粉末固结致密难度增加， 所需挤压力显著增大。
