Modeling Melt Spinning with Stress Induced Crystallization at High Take Up Velocities: Numerical Results for the PET Melt
(Asociación Argentina de Mecánica Computacional, 2002-11)
The purpose of this work is to present a 2-D thermo-rheological model for high take up velocities that can predict numerically in the filament domain, the axial velocity profile together with the radial and axial resolutions ...

Stress induced martensitic transformations and phases stability in Cu-Al-Be shape-memory single crystals
(Elsevier Science Sa, 2013-10)
The stress induced martensitic transformations between different metastable phases in Cu–Al–Be shapememory alloy single crystals were assessed experimentally. In particular, the successive stress induced transformations ...
Orientation dependence of the wear resistance in the Co–Cr–Mo single crystal
(2021-08-15)
This is the report clarifying the orientation dependence of the wear behavior of Co–Cr–Mo alloy. The wear resistance of the Co–Cr–Mo alloy with face-centered cubic (fcc) structure was found to be higher on the planes in ...
Martensitic transformation induced by void defects in the B2-CuZr crystal structure: an atomistic analysis
(TAYLOR & FRANCIS LTD, 2019)
Molecular dynamics simulations were carried out to perform tensile tests on B2-CuZr nanofilms at 1 K with a single spherical void defect. Six different samples were considered: a void-free one and five others with a single ...
Automatic devices for monitoring environmentally induced auto-oxidative degradation of artistic materials in conservation sites
(ELSEVIER SCIENCE SA, 2008)
This paper describes an automatic device for in situ and continuous monitoring of the ageing process occurring in natural and synthetic resins widely used in art and in the conservation and restoration of cultural artefacts. ...
Pseudoelastic Cycling between Austenite, 18R and 6R Phases in CuAlBe Single Crystals
(Elsevier, 2015-05)
CuAlBe shape memory alloys exhibit successive reversible stress induced martensitic transformations from austenite to 18R phase and from 18R to 6R phase. The particularities associated with these transformations result in ...
Phase transformation and residual stress probed by Raman spectroscopy in diamond-turned single crystal silicon
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2008)
Single-point diamond turning of monocrystalline semiconductors is an important field of research within brittle materials machining. Monocrystalline silicon samples with a (100) orientation have been diamond turned under ...
New deformation-induced nanostructure in silicon
(American Chemical Society, 2018-07)
Nanostructures in silicon (Si) induced by phase transformations have been investigated during the past 50 years. Performances of nanostructures are improved compared to that of bulk counterparts. Nevertheless, the confinement ...
Short-pulse laser-induced crystallization of intrinsic and hydrogenated amorphous germanium thin films
