Effect of sintering temperature on the mechanical properties of vacuum sintered Co-(Zn)-Ni-Al alloys
In the present study, the wear resistance behavior and the microhardness of the Co38Ni35Al27 and Co35Zn10Ni32Al23 ferromagnetic shape memory alloys (FSMAs) were investigated. The alloy samples were prepared by powder metallurgy method along with the vacuum sintering technique. The major aim...

description |
In the present study, the wear resistance behavior and the microhardness of
the Co38Ni35Al27 and Co35Zn10Ni32Al23 ferromagnetic shape memory alloys
(FSMAs) were investigated. The alloy samples were prepared by powder
metallurgy method along with the vacuum sintering technique. The major aim
is to prepare an alloy with high wear resistance having remarkable
microhardness suitable for the sustainable shape memory alloy. The wear test
report shows that the wear resistance is high for the sample sintered at 673
K and it gradually reduces when the sintering temperature decreases. The
result also shows that the inclusion of zinc in the alloy increases the wear
rate. The maximum hardness value of 126 HV was observed in Co38Ni35Al27
sample sintered at 673 K for 8 hrs because of its minimal porosity. |
