The magnetocaloric effect and critical behavior in amorphous Gd 60Co 40-xMn x alloys.
(AIP Publishing, 2012)
The amorphous alloys Gd60Co40−xMnx (x = 0, 5, 10, 15) were prepared by melt spinning. The Curie temperature,T c, increases monotonously with Mn addition, ranging from 198 K for x = 0 to 205 K for x = 15, while the maximum ...
Magnetocaloric effect and critical exponents of Fe77Co 5.5Ni5.5Zr7B4Cu1: A detailed study
(AIP Publishing, 2011-03-21)
The critical exponents of the alloy have been determined with the Kouvel–Fisher method to predict the field dependence of the magnetic entropy change DSM . The nonlinear fit of DSM ðHÞ to a power law provides a field ...
Influence of Mn on the magnetocaloric effect of nanoperm-type alloys
(AIP Publishing, 2010)
In this paper, the influence of the Mn content on the magnetocaloric response of ribbon-shaped amorphous samples of Fe80−xMnxB20 x=10, 15, 18, 20, and 24 , has been studied. For this purpose, the temperature and field ...
Mechanical behavior of single-layer ceramized zirconia abutments for dental implant prosthetic rehabilitation
(Medical Oral Sl, 2014)
Objectives: This study was undertaken to characterize the mechanical response of bare (as-received) and single layer ceramized zirconia abutments with both internal and external connections that have been developed to ...
Flue gas adsorption by single-wall carbon nanotubes: A Monte Carlo study
(American Institute of Physics Publising LLC, 2016)
Adsorption of flue gases by single-wall carbon nanotubes (SWCNT) has been studied by means of Monte Carlo simulations. The flue gas is modeled as a ternary mixture of N2, CO2, and O2, emulating realistic compositions of ...
Magneto-caloric effect in the pseudo-binary intermetallic YPrFe17 compound
We have synthesized the intermetallic YPrFe17 compound by arc-melting. X-ray and neutron powder diffraction show that the crystal structure is rhombohedral with View the MathML source space group (Th2Zn17-type). The ...
Avalanche criticality in the martensitic transition of Cu67.64 Zn16.71 Al15.65 shape-memory alloy: A calorimetric and acoustic emission study
(American Physical Society, 2010)
The first-order diffusionless structural transition in Cu67.64 Zn16.71 Al15.65 is characterized by jerky propagation of phase fronts related to the appearance of avalanches. In this paper, we describe a full analysis of ...
Technological proposals for recycling industrial wastes for environmental applications
A two-fold objective is proposed for this research: removing hazardous and unpleasant wastes and mitigating the emissions of green house gasses in the atmosphere. Thus, the first aim of this work is to identify, characterize ...
Universal behavior for magnetic entropy change in magnetocaloric materials: An analysis on the nature of phase transitions
(The American Physical Society, 2010-06-16)
A universal curve for the change in the magnetic entropy has been recently proposed for materials with second-order phase transitions. In this work we have studied the universal behavior of the magnetocaloric effect in the ...
The magnetocaloric effect of partially crystalline Fe-B-Cr-Gd alloys.
(AIP Publishing, 2012)
The influence of annealing temperature and crystallization on the magnetocaloric effect (MCE) of Fe-B-Cr-Gd partially crystalline alloys was studied. Although the alloys exhibited dissimilar devitrification behavior, all ...
