In the present paper, a complete literatures review of thermal barrier coating applications in diesel engines is performed to select a proper type and to find coating effects. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of engine components. Usually there are several beneficial influences by appl...

In the past several years the cyclic nature of Heat Recovery Steam Generators, HRSG’s, has increased dramatically. There are many methods for evaluating cyclic service. Several methods for evaluating cycle life are compared for their use on HRSG’s. A discussion of strengths and weaknesses of each method is presented. INTRODUCTION ASME Section I [1] and Section VIII, Division 1 [2], do not provi...

Stainless steels are the most exploited materials due to their high mechanical strength and versatility in producing different alloys. Although there is great interest in these materials, mechanical characterisation, in particular fatigue characterisation, requires the application of several standardised procedures involving expensive and time-consuming experimental campaigns. As a matter of fa...

Nickel-base superalloys have become the key materials of hot-end components in the aeroengines over the past several decades. Nickelbase superalloys are easy to produce thermo-mechanical fatigue (TMF) behavior when withstanding the combined effects of high temperature, creep, oxidation, mechanical stress and thermal stress. The occurrence of TMF seriously affects the normal service for hot-end ...

Participants in prolonged, physically demanding cold-weather activities are at risk for a condition called "thermoregulatory fatigue". During cold exposure, the increased gradient favoring body heat loss to the environment is opposed by physiological responses and clothing and behavioral strategies that conserve body heat stores to defend body temperature. The primary human physiological respon...

The thermo mechanical reliability of plated through holes (PTH) in printed circuit boards (PCB) normally is determined by different tests (e.g. thermo cycle test (TCT), interconnect stress test (IST), highly accelerated thermal shock (HATS). During these tests the PTH Cu is exposed to stresses and strains which are below the tensile strength and the fracture strain, respectively, which leads to...
