Characterization of mechanical relaxation in a Cu-Zr-Al metallic glass
Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2015-09-15)
Article
Accés obertThe temperature dependence of the relaxation times of Cu46Zr46Al8 glass was measured by means of mechanical spectroscopy and static stress-relaxation measurements. The weak intensity of secondary relaxation in this alloy ... -
Dynamics of metallic glasses explored by mechanical relaxation
Liu, Chaoren (Universitat Politècnica de Catalunya, 2015-10-07)
Tesi
Accés obertDynamic mechanical analysis (DMA) is often used to explore the relaxation dynamics of metallic glasses (MGs). Secondary relaxations in metallic glasses appear as an excess wing, as a shoulder of the primary relaxation peak ... -
Materials, techniques, and conservation of historic stained glass "Grisailles"
Pradell Cara, Trinitat; Molina Giralt, Glòria; Murcia, Sonia; Ibáñez De Aldecoa, Rafael; Liu, Chaoren; Molera Marimon, Judit; Shortland, A.J. (2016-03-01)
Article
Accés restringit per política de l'editorialA grisaille is a brown-blackish paint applied onto the inner surface of stained glass to draw the contours and details of the figures and to produce the effect of shades and volumes. Grisailles were traditionally made of ... -
Mechanical relaxation of metallic glasses: an overview of experimental data and theoretical models
Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2015-06)
Article
Accés obertRelaxation phenomena in glasses are a subject of utmost interest, as they are deeply connected with their structure and dynamics. From a theoretical point of view, mechanical relaxation allows one to get insight into the ... -
Modeling of the Sub-Tg Relaxation Spectrum of Pd42.5Ni7.5Cu30P20 Metallic Glass
Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel; Qiao, Jichao (2016-03-17)
Article
Accés obertIn this work we study the mechanical relaxation spectrum of Pd42.5Ni7.5Cu30P20 metallic glass. The effect of aging on the relaxation behavior is analyzed by measuring the internal friction during consecutive heating runs. ... -

Article
Accés obertWe present a temperature investigation of the structural and dynamical evolution of rapidly quenched metallic glasses of Mg65Cu25Y10 at the atomic length scale by means of in situ high energy x-ray diffraction and time ... -
Sub-T-g relaxation times of the alpha process in metallic glasses
Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel; Qiao, Jichao; Evenson, Zach; Ruta, Beatrice (2017-09-01)
Article
Accés obertThe current view of structural relaxation in metallic glasses assumes the presence of primary and secondary processes with different activation energies. While the faster, secondary process can be well characterized in the ...
