Nanostructured Single Crystals Sandwiched between Ordered/Disordered Coily and Rod Brushes

Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding methodology. The PS and PMMA grafted chains were categorized in disordered nano-brushes; however, the PCL and PANI ones were grouped in ordere...

Cyclic deformation behavior of high-purity titanium single crystals: Part II. Microstructure and mechanism

Pseudoelastic Deformation of CuAlMn Single Crystals

Martensitic transformation associated with a tensile deformation of CuAlMn single crystals in [loo] direction was studied using in-situ transmission electron microscopy. Stress/strain curves obtained during pseudoelastic deformation of microscopic samples were slightly different fiom bulk ones due to martensite formation in the stage of stress increase and a permanent deformation during the fir...

Plastic deformation of CoO single crystals

2014 Constant strain rate compressions along 001 &#x3E; have been performed on CoO single crystals (03B5 ~ 6 x 10-5 s-1). Yield stresses and work hardening rates have been measured between 77 K and 1 400 K; CoO is very strong when compared to similar compounds. Vickers indentations have been performed on { 100 }, { 110 } and { 111 } faces around the Néel temperature, i.e. between 0 °C and 40 °C...

Plastic deformation of single nanometer-sized crystals.

We report in situ electron microscopy observations of the plastic deformation of individual nanometer-sized Au, Pt, W, and Mo crystals. Specifically designed graphitic cages that contract under electron irradiation are used as nanoscopic deformation cells. The correlation with atomistic simulations shows that the observed slow plastic deformation is due to dislocation activity. Our results also...
