On the Thermal Cycling and Evolution of Surface Morphology for Thermally Cycled NiCoCrAlY Bondcoats

2008
Morphological instabilities such as rumpling and ratcheting on bond coat surfaces in thermal barrier coatings (TBCs) have recently received significant attention since these phenomena can be directly linked to system failures. Recent observations from thermomechanically cycled TBC-samples reveal that, if the ceramic top coat has spalled, the ...

A Thermal Control System for Thermal Cycling

Journal of Testing and Evaluation, 1985
Abstract A microprocessor-based system has been developed to control varying temperature during material characterization tests. The system controls temperature independently over four zones. Four control zones are used in order to provide two-dimensional temperature control on a flat plate specimen.

Petrological and ultrasonic velocity changes of coals caused by thermal cycling of liquid carbon dioxide in coalbed methane recovery

Fuel, 2019
Enhanced coalbed methane (CBM) recovery by injecting liquid CO2 (LCO2) has been a promising research topic for decades. Although the phase-fracturing and blooding effect during injection have been studied, the non-isothermal impact of cryogenic fluids on

Thermal cycle dideoxy DNA sequencing

Molecular Biotechnology, 1996
Thermal cycle dideoxy DNA sequencing eliminates the requirements for independent primer annealing and double-stranded DNA denaturation steps. The method enables sequencing from nanogram amounts of DNA from double-stranded and single-stranded PCR products, and plasmid or phage DNA templates.

Comparison of power cycling and thermal cycling effects on the thermal impedance degradation in IGBT modules

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
Insulated gate bipolar transistor (IGBT) devices have gained leading position in traction and aerospace applications. The failure of these switches (IGBT) can reduce the efficiency of the system. Two most dominated failure mechanisms of IGBTs are solder fatigue and bond wire lift off. One of the major effects which influence these failure mechanisms is
