Enhanced magnetocaloric response in Cr/Mo containing Nanoperm-type amorphous alloys
(AIP Publishing, 2007-02-01)
The magnetocaloric effect of Fe76Cr8−xMoxCu1B15 (x =0,4) alloys is studied. Although the combined addition of Cr and Mo is more efficient in tuning the Curie temperature of the alloy, the Mo-free alloy presents a higher ...
Comparison of equivalent ball milling processes on Fe70Zr30 and Fe70Nb30
Dynamical analysis of the movement of a single ball in a planetary ball mill yields a cubic law with the frequency of the mill for the power released during the process. This fact has been explored for two binary compositions ...
The influence of Co addition on the magnetocaloric effect of Nanoperm-type amorphous alloys
(AIP Publishing, 2006-09-22)
The effect of Co addition on the magnetocaloric effect of amorphous alloys with Nanoperm-type composition has been studied for temperatures above room temperature. Co addition produces an increase in the maximum magnetic ...
Influence of Mn content on the microstructure and hyperfine interaction parameters of amorphous and nanocrystalline Hitperm-type FeCoMnNbB alloys.
(Russian Academy of Sciences, 2008)
Effects of Mn addition on the devitrification kinetics, microstructure and hyperfine inter- action parameters of FeCoMnNbB alloys were investigated. As-cast and nanocrystalline samples were studied by different experimental ...
A constant magnetocaloric response in FeMoCuB amorphous alloys with different FeB ratios
(AIP Publishing, 2007-05-04)
The magnetocaloric effect of Fe91−xMo8Cu1Bx (x = 15 , 17 , 20) amorphous alloys has been studied. The temperature of the peak of magnetic entropy change can be tuned by altering the Fe / B ratio in pk pk the alloy, without ...
Influence of Co and Ni addition on the magnetocaloric effect in Fe88−2xCoxNixZr7B4Cu1 soft magnetic amorphous alloys
(AIP Publishing, 2010)
We have studied the magnetocaloric effect in a series of Fe88−2xCoxNixZr7B4Cu1Fe88−2xCoxNixZr7B4Cu1alloys. The partial substitution of Fe by Co and Ni leads to a monotonic increase in the Curie temperature(TC)(TC) of the ...
On the use of JMAK theory to describe mechanical amorphization: a comparison between experiments, numerical solutions and simulations
The kinetics of amorphization during ball milling is generally analyzed using two different approaches: the classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory and Delogu and Cocco’s model for which a region ...
