Novel TiNiCuNb shape memory alloys with excellent thermal cycling stability
Journal of Alloys and Compounds, 2019The thermal cycling stability of martensitic transformation in (Ti54Ni34Cu12)100-xNbx (x = 0, 6 and 10 at.%) was investigated. The results show that doping Nb into Ti54Ni34Cu12 enhances the thermal cycling stability of the material.

Laser cycling and thermal cycling exposure of thermal barrier coatings on copper substrates
Surface and Coatings Technology, 2011Abstract Thermal barrier coatings (TBCs) are successfully applied in turbines and could also protect combustion chambers in rocket engines. Apart from different loading conditions, the main difference between these applications is the substrate material, which is nickel-based for turbines and copper-based for rocket engines.

Capillary Tube Resistive Thermal Cycling
Analytical Chemistry, 1998A system that performs rapid thermal cycling of microliter and smaller liquid volumes inside glass capillary tubes that have an optically transparent thin film of indium-tin oxide (ITO) covering the exterior is described. The ITO film acts as both a heater and a temperature sensor, while cooling is accelerated with forced air.

Lifetime prediction of thermoelectric devices under thermal cycling
Journal of Power Sources, 2019Thermoelectric (TE) devices under thermal cycling are prone to interface defects. Based on the experimental observation, this paper proposes a generalized model to analyze the interface damage growth and predict the lifetime of thermoelectric (TE ...

A thermal cycle in the atmosphere
Geofisica pura e applicata, 1952It is shown that in order for a steady-state closed circulation to be maintained in the atmosphere, the working of the pressure force on a particle moving round the closed circuit is exactly balanced by the working of the particle against friction.

On-off operation of electronic systems leads to thermal cycling, which introduces thermal and strain energy into solder joints, resulting in microstructural evolution mechanisms of recovery, recrystallization and damage nucleation. The thermal strain history is very sensitive to the package design.
