The influence on the mobility of polypeptide chains caused by strain misfit due to molecular electric dipole distortions under applied fields up 769 kV m-1, in cow cortical femur samples annealed at 373 K, 423 and 530 is determined. behaviour as a function field strength determined from mean-field model based Eshelby theory. In addition, Friedel's for describing dislocations continuum media has been modified determine interaction energy between electrically generated obstacles chains....
Abstract The capacity of adaptability a three-dimensional-printed composite polycaprolactone-based containing micro-particles ferromagnetic shape memory alloy composition Ni 45 Mn 36.7 In 13.3 Co 5 was determined. Composites exhibit an increase in both damping and modulus values up to around 11%, at temperatures close 325 K, when applying magnetic field 120 kA m −1 . addition, composites show also the 50% near 333 related martensitic transformation, which is promoted by oscillating strain...

The production of μ-particles Metamagnetic Shape Memory Alloys by crushing and subsequent ball milling process has been analyzed. high energy involved in the induces large internal stresses density defects with a strong influence on martensitic transformation; interphase creation its movement during transformation produces frictional contributions to entropy change (exothermic process) both forward reverse transformation. contribution increases time as consequence interaction between...
Abstract A high filling load (62% weight) printable magnetic composite has been elaborated from the dispersion of magnetocaloric Ni 45 Mn 36.7 In 13.3 Co 5 metamagnetic shape memory alloy microparticles into a PCL polymer matrix. The material prepared by solution method, resulting in very homogeneous particles structural transitions are not affected addition metallic microparticles, which turn results significant increase mechanical consistency. good ductility allows its extrusion flexible...
The mobility of twin boundaries in (at.%) Fe70Pd30, Fe67Pd30Co3 and Fe66.8Pd30.7Mn2.5 has been studied by mechanical spectroscopy. Measurements were carried out amplitude dependent damping regime. A new model based on the Friedel theory was developed to obtain activation energy (～2 kJ/mol) for motion. describes from thermally assisted break-away dislocations. Interaction processes among boundaries, dislocations vacancies during recovery structure are also discussed. Moreover, a peak related...
The wide damping maximum which is reported to appear in bones, involving both cortical and cancellous parts, between around 280 K 420 K; has been determined be a composition of different processes taking place at temperatures parts. In fact, the present work mechanical response cow ribs bones analysed by coupling spectroscopy, differential scanning calorimetry, thermogravimetry electron microscopy studies. Cancellous part develops two maxima 320 350 K. Cortical exhibits 310 410 another...

The behaviour of damping and dynamic shear modulus in polypropylene charged with either different volume fraction or size magnetite (Fe3O4) particles, as a function the applied magnetic field at 318, 353 403 K; has been studied. An increase alternating oscillating 50 Hz, leads to an damping. In addition, during subsequently decreasing field, decreases, but hysteretic appeared. elastic under application was explained by development fatigue damage occurring around particle interface due...
The viscoelastic properties (E', G', tanΦ, δ) of Arundo donax (AD) and a polypropylene-beech fiber composite (PPC) were measured from RT to 580K for various frequencies strains. E' AD varies between 5250-6250MPa depending on ageing at while E'(RT)=2250MPa PPC is signifcantly lower. the higher than in whole investigated temperature range with exception after heat treatment up 575K. Damping spectra exhibit peaks around 340K (Q=234kJ/mol) 415K related relaxations crystalline part polypropylene...
The thermal stability of collagen is great interest for the scientific communities both medicine and archaeology. In medicine, focused to reconstruction repair bone cartilage, given frequency importance pathological situations. contrast, in archaeology infer from buried and/or burned bones behavior habits people who once inhabited archaeological sites. cow ribs, biodegradation by denaturation albumin haemoglobin proteins, loss water crystallization during warming up around 450 K, have been...
ABSTRACT Aging treatments in water and air controlled neutron irradiation were performed on commercial crosslinked low‐density polyethylene (XLPE) for promoting different mesostructural arrangements of crystallites crosslinking degree.

Amplitude dependent damping and neutron thermo-diffraction studies were performed in Fe-Al-Si, Fe-Al-Cr Fe-Si alloys. Results show that the behaviour of strength amplitude as a function temperature is suitable tool for determining order changes temperature. A decrease degree leads to an increase damping, due dislocation mobility increases.
In the present work value of degree area swept by polymer chain due to an electrical force for a given mesostructure was related corresponding dielectric strength. This deduced from electric inclusion formalism applied dynamic mechanical analysis (DMA) studies conducted under high field, which were performed in commercial ethylene-propylene-diene M-class rubber (EPDM); used housing polymeric insulators. EPDM samples with different arrangements chains and crystalline degree, promoted...

The behavior of internal friction Q -1 and dynamic shear modulus has been studied in polypropylene charged with either different volume fraction or size magnetite (Fe 3 O 4 ) particles, as a function the applied magnetic field at 318 K. An increase alternating (AC) oscillating 50 Hz, leads to an friction. In addition, during subsequently decreasing field, decreases, but hysteretic appeared. fact, part amplitude is found be smaller than previously increasing treatment field. Subsequent...
Iron-Aluminium alloys were produced by the electro-deposition of iron-aluminium on a copper substrate. The process was done in ionic liquid 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate, [Py1,4]TfO. A solution (0.2 M FeCl2 + 2.75 AlCl3)/ [Py1,4] TfO used at temperature T=363 K because this mixture is solid room temperature. Electrodeposited samples studied means mechanical spectroscopy, differential thermal analysis and laser light microscopy. Mechanical spectroscopy studies...
