- •
The grain size and cell volume of Al8Mn5 alloy phase were decreased with the increasing of Ni.
- •
ε″ and μ″ of powder moves toward low frequency region at the beginning then moves high.
- •
The minimum reflectivity of (Al8Mn5)0.95Ni0.05 powder was −40.8 dB with 1.8 mm thickness.
- •
The lowest reflection loss peak of (Al8Mn5)0.95Ni0.05 was −46.3 dB with 2.2 mm thickness.
