High temperature internal friction in a Ti–46Al–1Mo–0.2Si intermetallic, comparison with creep behaviour
(Elsevier, 2016-01-15)
Advanced gamma-TiAl based intermetallics Mo-bearing have been developed to obtain the fine-grained microstructure required for superplastic deformation to be used during further processing. In the present work we have ...
Stress-assisted atomic diffusion in metastable austenite D03 phase of Cu-Al-Be shape memory alloys
(Pergamon-Elsevier, 2016-11)
Cu-Al-based shape memory alloys are firm candidates to be used up to 473 K. The main limiting aspect is the activation of diffusion processes in the metastable austenite phase, which drive the alloy decomposition. In the ...
Thermo-radiative and optical properties of a cutting tool based on polycrystalline cubic boron nitride (PCBN)
(IOP Publishing, 2016-04-27)
The normal spectral emissivity of a cutting tool based on polycrystalline cubic boron nitride (PCBN) between 400 °C and 1000 °C has been measured. Its shape shows significant differences with respect to that of pure cubic ...
Thermal emissivity spectra and structural phase transitions of the eutectic Mg-51%Zn alloy: A candidate for thermal energy storage
(Elsevier, 2016-11-05)
The thermal emissivity spectrum in the mid infrared range (3–21 μm) as well as its dependence on temperature between 225 and 320 °C has been obtained for the Mg-51%Zn (weight %) eutectic alloy, a candidate for thermal ...
