Study of the influence of simultaneous variation of magnetic material microstructural features on domain wall dynamics
(ELSEVIER SCIENCE BV, 2010)
The magnetic Barkhausen noise (MBN) is a phenomenon sensitive to several kinds of magnetic material microstructure changes, as well as to variations in material plastic deformation and stress. This fact stimulates the ...
The influence of deformation path on strain characteristics of AA1050 aluminium processed by equal-channel angular pressing followed by rolling
(Elsevier Science Sa, 2015-10)
The present investigation reports on the microstructure evolution, texture development, the nature of the grain boundaries and the tensile and deep drawing behaviour of commercial AA1050 Al processed by Equal Channel Angular ...
Atomistic simulation of the mechanical properties of nanoporous gold
(Elsevier, 2014-08)
7–109 s−1 using molecular dynamics simulations. We consider the low-porosity regime (porosity of ∼5%), which is characterized by several stages of plastic deformation. At the onset of plasticity, pores act as if isolated ...
Deformação plástica severa da liga Ti-13Nb-13Zr
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2017-03-03)
Biomedical devices currently in use (prostheses, implants) have satisfactory performance in many cases. However, sometimes the body reacts to the device insertion and may lead to its rapid replacement. Some of these ...
Engineering of surface microstructure transformations using high rate severe plastic deformation in machining
(UniandesDoctorado en IngenieríaFacultad de Ingeniería, 2015)
Engineering surface stuctures especially at the nanometer length-scales can enable fundamentally new multifunctional property combinations, including tunable physical, mechanical, electrochemical and biological responses. ...
Microstructural Evolution of Ti-6Al-7Nb Alloy During High Pressure Torsion
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2014)
Microstructural Evolution of Ti-6Al-7Nb Alloy During High Pressure Torsion
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-09-01)
Ti-6Al-7Nb alloys are being evaluated for biomedical applications, in substitution of the more conventional Ti-6Al-7V. Both types of alloys present a microstructure containing the alpha and the beta phases, which result ...

Ultrahigh hardness and biocompatibility of high-entropy alloy TiAlFeCoNi processed by high-pressure torsion
(2020-07-01)
Despite significant studies on mechanical properties of high-entropy alloys (HEAs), there have been limited attempts to examine the biocompatibility of these alloys. In this study, a lattice-softened high-entropy alloy ...
