On the Mechanism of Pinning in Phase-Separating Polymer Blends

open access: yes, 1995
We re-explore the kinetics of spinodal decomposition in off-critical polymer blends through numerical simulations of the Cahn-Hilliard equation with the Flory-Huggins-De Gennes free energy functional. Even in the absence of thermal noise, the solution of

Impact of Pre‐Oxidation Treatments on a Recycled MgO/Steel‐Composite as Carbon Free Anode in Aluminum‐Electrolysis Environments

open access: yesAdvanced Engineering Materials, EarlyView.
Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Thermal decomposition analysis of simulated high-level liquid waste in cold-cap

open access: yesEPJ Nuclear Sciences & Technologies, 2016
The cold cap floating on top of the molten glass pool in liquid fed joule-heated ceramic melter plays an important role for operation of the vitrification process. A series of such phenomena as evaporation, melting and thermal decomposition of HLLW (high-

Thermochemistry of yavapaiite KFe(SO4)2: Formation and decomposition [PDF]

open access: yes, 2005
Yavapaiite, KFe(SO4)2, is a rare mineral in nature, but its structure is considered as a reference for many synthetic compounds in the alum supergroup. Several authors mention the formation of yavapaiite by heating potassium jarosite above ca. 400°C. To

Additive Manufacturing of Continuous Fibre Reinforced Composites: Process, Characterisation, Modelling, and Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing provides precise control over the placement of continuous fibres within polymer matrices, enabling customised mechanical performance in composite components. This article explores processing strategies, mechanical testing, and modelling approaches for additive manufactured continuous fibre‐reinforced composites.

Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

Thermal hazard assessment and free radical inhibition of decomposition of tert-butyl perbenzoate

open access: yesEmergency Management Science and Technology
Tert-butyl perbenzoate (TBPB) is a common initiator widely used in polymerization processes, but the peroxide bond in its molecular structure is highly susceptible to breakage, leading to decomposition or even explosion.
