Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Calling behavior of the female carob moth, Ectomyelois ceratoniae (Lepidoptera: Pyralidae) under cycling and constant temperatures in laboratory

Journal of Crop Protection, 2013
The calling behavior of virgin carob moth females, Ectomyelois ceratoniae (Zeller) (Lep.: Pyralidae) was evaluated under two different thermal regimes, cycling and constant temperatures under laboratory condition.

Characteristics of thermal cycling in a magnesium alloy

, 2002
Acoustic emission (AE) and dilatometry were used to monitor the internal thermal stresses and the related structural changes and matrix plastic deformation induced in a magnesium-based composite during thermal cycling.

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Simulating Thermal Cycling and Isothermal Deformation Response of Polycrystalline NiTi

, 2011
A microstructure-based FEM model that couples crystal plasticity, crystallographic descriptions of the B2-B19' martensitic phase transformation, and anisotropic elasticity is used to simulate thermal cycling and isothermal deformation in polycrystalline ...

Thermal cycling of Mg-MMCs

, 2003
Creep resistant Mg alloy QE22 reinforced with maftec(R), saffil(R) or supertec(R) short fibres is cycled between room temperature and 308degreesC at different ramp rates in the longitudinal and transverse directions.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Numerical simulations of the influence of thermal cycling parameters on the mechanical response of SAC305 interconnects

Journal of the Mechanical Behavior of Materials
Electronic assemblies are continuously subjected to cyclic thermal loadings during operation, which can lead to fatigue failures in solder interconnections. A typical thermal cycle is characterized by high and low dwell temperatures, dwell durations, and

Thermal cycling damage of silica refractories for high-temperature thermal energy storage (HT-TES) – Can it be healed?

Open Ceramics
Silica refractories are promising materials for high-temperature thermal energy storage (HT-TES), because they exhibit excellent thermal cycling properties, unless cooled below a critical temperature (usually assumed to be 600 °C).

A laser thermal cycling rig as a new method to characterize the evolution of coating adhesion under thermal cycle

, 2012
Thermal sprayed coatings are often used for high temperature applications and, per se, are subjected to transient temperature gradients during operation.
