Timescales of crystallization and viscous flow of the bulk glass-forming Zr-Ti-Ni-Cu-Be alloys [PDF]

, 2003
Crystallization behavior and equilibrium viscosity of a series of alloys in the Zr-Ti-Cu-Ni-Be system are studied using multiple techniques to determine the various contributions to glass-forming ability.

Study of low-temperature isothermal annealing in the PM Cu-Pt alloys after plastic deformation [PDF]

Tehnika, 2020
The investigation was performed on pure sintered (PM) copper and dilute PM copper-based alloys with 3 and 5.9 wt.% of platinum. Investigated PM samples were obtained using the standard powder metallurgy technique by mixing the elemental powders in proper

Thermal stability of thin rolled potassium-doped tungsten sheets during annealing at temperatures up to 1400 °C

Nuclear Materials and Energy, 2022
Microstructural changes will occur in tungsten when used as plasma-facing material in future fusion reactors due to the high operation temperatures. Potassium doping has proven to delay such undesired changes in drawn tungsten wires. The same strategy is

Cure kinetics of ring-opening metathesis polymerization of dicyclopentadiene [PDF]

, 2002
The cure kinetics of polydicyclopentadiene (pDCPD) prepared by ring-opening metathesis polymerization with three different concentrations of Grubbs' catalyst was examined using differential scanning calirimetry (DSC).

Compound Growth due to Isothermal Annealing of Cu-Clad Al Wire

MATERIALS TRANSACTIONS, 2019
To better understand the annealing mechanisms that occur in Cu-clad Al (CA) wire, the solid-state reactive di ff usion between Cu and Al was experimentally examined by a metallographical technique.

Thermal stability of Hg1-xMnxTe compound semiconductors [PDF]

, 1992
The thermal behaviour of Hg1-xMnxTe single crystals is investigated by means of the RBS/channeling technique. The stoichiometry parameter x ranges from 0.08 to 0.2.

Experimental determination of a time–temperature-transformation diagram of the undercooled Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 alloy using the containerless electrostatic levitation processing technique [PDF]

, 1996
High temperature high vacuum electrostatic levitation was used to determine the complete time–temperature–transformation (TTT) diagram of the Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 bulk metallic glass forming alloy in the undercooled liquid state.

Secondary Crystallization of Isotactic Polystyrene [PDF]

, 1974
When isotactic polystyrene (i-PS) is crystallized from the melt or from the glassy state at rather large supercooling an additional melting peak appears on the curve during scanning in a differential calorimeter.

Isothermal self-assembly of multicomponent and evolutive DNA nanostructures

Nature Nanotechnology, 2023
Thermal annealing is usually needed to direct the assembly of multiple complementary DNA strands into desired entities. We show that, with a magnesium-free buffer containing NaCl, complex cocktails of DNA strands and proteins can self-assemble ...

Tuning the microstructure and mechanical properties of TiAl-based alloy through grain boundary engineering

Journal of Materials Research and Technology, 2022
In order to modify the room-temperature plasticity of TiAl-based alloy, grain boundary character distribution (GBCD) in TiAl-based alloy was tuned through multidirectional isothermal forging (MDIF) combined with annealing. The experimental results showed
