Uji Kekerasan pada Paduan Fe-50%atAl dengan Penambahan Nikel Menggunakan Metode Mechanical Alloying
Abstract: Hardness test on the
alloy Fe-50% at Al with the addition of nickel were prepared by mechanical
alloying method. The powder mixture Fe-50at.%Al with the variation adding
0,5at.%Ni, and 2at.%Ni are grinded using High Energy Milling HEM E-3D in Argon
condition for 10 hours. To determine the hardness, conducted to take the sample
with the certain time duration to each composition. Then, the sample which has
been taken is characterization using hardness. The results showed that the
highest hardness properties exist in the alloy Fe-50% at Al-0.5% at Ni,
amounting to 161.53 HV. The addition of nickel on alloy reduces the hardness
properties of the alloy. However, the addition of nickel require a short time
to raise the hardness properties.
