Eletrodeposição de ligas bioabsorvíveis do sistema Fe-Mn
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2019-03-25)
Stents are medical devices which promote the opening and mechanical support of clogged blood vessels and, once applied, cannot be removed. The manufacture of bioabsorbable stents is desirable to avoid several subsequent ...
Comparison of corrosion resistance of a Fe-Mn-Al alloy boronized by pack or salt bath process
(2010-12-01)
Fe-Mn-Al alloys have been developed to replace traditional stainless steel in some applications, in less severe corrosive environments. In this work, an alloy of this class was subjected to two different boronizing treatments, ...
Is it Possible to Use Rolling Methods to Improve Textures on Fe-Mn-Si Shape Memory Alloys?
(Wiley VCH Verlag, 2017-04)
No uniform rolling deformation produces shear strains that give rise to textural and microstructural heterogeneities in processed metals and alloys. In this work, the authors investigate Fe-30Mn-4Si shape memory alloy ...
Influence of thermal treatments on the mechanical properties and the martensitic transformation in Fe-Pd-Mn ferromagnetic shape memory alloy
(Elsevier Science Sa, 2017-01)
The effects of high temperature thermal treatments on the hardening behaviour, the damping capacity and the martensitic transformation in Fe66.8Pd30.7Mn2.5 Ferromagnetic Shape Memory Alloy have been determined by mechanical ...
Effect of lattice defects on shape memory properties of Fe-Mn-Si alloysEfecto de los defectos cristalinos sobre las propiedades de memoria de forma de las aleaciones Fe-Mn-Si
(Comité Interamericano de Sociedades de Microscopía Electrónica, 2010-01-29)
We have investigated two shape memory ferrous alloys, Fe-30Mn-4Si and Fe-15Mn-4Si-9Cr-5Ni, processed by different thermo-mechanical ways, in order to analyze the effect of processing conditions and the stacking fault energy ...
Measurement of Stark broadening of Mn I and Mn II spectral lines in plasmas used for Laser-Induced Breakdown Spectroscopy
(Pergamon-Elsevier Science Ltd, 2007-12)
We present measurements of the Stark broadening of several Mn lines in the conditions of typical laser-induced plasmas. Single-and double-pulse Laser-Induced Breakdown spectroscopy (LIBS) configurations are studied on a ...
Composition dependence of the Néel temperature and the entropy of the magnetic transition in the fcc phase of Fe-Mn and Fe-Mn-Co alloys
(Elsevier Science Sa, 2016-07-21)
A key feature of the fcc-to-hcp martensitic transformation (MT) in Fe-Mn based alloys is that the fcc structure is strongly stabilized by a paramagnetic-to-antiferromagnetic ordering reaction, which partially or completely ...
Effects of coexisting spin disorder and antiferromagnetism on the magnetic behavior of nanostructured (Fe79Mn21)1xCux alloys
(American Institute of Physics, 2014-06)
We report a magnetic study on nanostructured (Fe79Mn21)1xCux (0.00x0.30) alloys using static magnetic measurements. The alloys are mainly composed by an antiferromagnetic fcc phase and a disordered region that displays a ...
Texture analysis of cold rolled and annealed aluminum alloy produced by twin-roll casting
(ABM, ABC, ABPol, 2012)
A 7.4 mm thick strip of 3003 aluminum alloy produced by the industrial twin-roll casting (TRC) process was homogenized at 500 °C for 12 hours, after which it was cold rolled in two conditions: 1) to reduce the strip's ...
