Thermal characterization of Cu60ZrxTi40−x metallic glasses (x=15, 20, 22, 25, 30)

Effect of relaxation and primary nanocrystallization on the mechanical properties of Cu60Zr22Ti18 bulk metallic glass

“…The amorphous nature of the alloys was confirmed by X-ray diffraction (XRD) and differential scanning calorimetry (DSC) as described in [12]. DSC measurements were carried out in a Perkin-Elmer DSC-7 under a dynamic pure argon atmosphere.…”

“…Previous studies on the Cu 60 Zr x Ti 40-x (xZ15, 20,22,25,30) amorphous system showed for xZ22, the widest supercooled liquid region and the highest glass forming ability [12]. The present work is a first approach in the analysis of the mechanical response of the Cu 60 Zr 22 Ti 18 BMG and the effect produced by different thermal Intermetallics 13 (2005) treatments, and therefore, changes in the structure of the amorphous material, on its mechanical behaviour.…”

Estimation of heat production during high pressure torsion of Cu-based metallic glass

“…4a) due to the strong temperature dependence of the viscosity. Thereafter, the temperature shows only a small increase (∼10 K) and remains well below the liquidus temperature (T l = 1192 K [19]) until the HPT process is complete. Based on the temperature evolution in the HPT sample, the characteristic time t*(r) required to reach T g is plotted in Fig.…”

Anelastic deformation of a Pd40Cu30Ni10P20 bulk metallic glass during nanoindentation

“…Some bulk metallic glasses ͑BMGs͒ and amorphous ribbons exhibit outstanding mechanical properties, [1][2][3][4][5] and good corrosion and wear resistance. 6 This makes them attractive as structural materials.…”
