Fatigue Crack Growth Behavior of Nickel-base Superalloy Haynes 282 at 550-750° C

Creator:: Rozman, K. A., Kruzic, J. J., and Hawk, J. A.
Abstract:: The fatigue crack growth rates for nickel-based superalloy Haynes 282 were measured at temperatures of 550, 650, and 750 °C using compact tension specimens with a load ratio of 0.1 and cyclic loading frequencies of 25 Hz and 0.25 Hz. Increasing the temperature from 550 to 750 °C caused the...

Fatigue Crack Growth Mechanisms for Nickel-based Superalloy Haynes 282 at 550-750° C

Creator:: Rozman, Kyle A., Kruzic, Jamie J., Sears, John S., and Hawk, Jeffrey A.
Abstract:: The fatigue crack growth rates for nickel-based superalloy Haynes 282 were measured at 550, 650, and 750 °C using compact tension specimens with a load ratio of 0.1 and cyclic loading frequencies of 25 and 0.25 Hz. The crack path was observed to be primarily transgranular for all temperatures, and...

Characterization of high temperature fatigue mechanisms in Haynes 282 nickel based superalloy

Creator:: Rozman, Kyle A.
Abstract:: Electric power needs will only grow over the next decades as more humans ascend from poverty into the middle class. Currently, the majority of electric power is generated by burning fossil fuels. To help mitigate the undesirable effects of burning fossil fuels research is being done to increase the efficiency...

Time-Dependent Crack Growth Mechanisms in Alloy 617 at 800°C in Air

Creator:: Addison, Dylan, A.
Abstract:: Time-dependent crack growth mechanisms in Alloy 617 at 800°C in air were studied using compact tension samples machined in the L-T direction, cracked at temperature using an induction furnace and servo-hydraulic load frame. The application of different loading waveforms, including triangular, hold time, and sustained loading, were studied with relation...

Characterization and Development of Ni-based Superalloys for Supercritical Carbon Dioxide Applications

Creator:: Adam, Benjamin M.
Abstract:: The advent of supercritical CO2 as a new heat-exchange medium has seen strong interest from the power industry and the energy research field recently. It is advan- tageous in comparison with other heat-exchange cycles, as it can be operated safely at much higher temperatures and pressures, thus increasing the thermal...

The effect of elevated temperature on mechanical behavior of structural wood and wood-based composites

Creator:: Sinha, Arijit
Abstract:: Engineers, in practice, are often faced with the challenge of evaluating a fire-damaged structure and developing a rehabilitation and retrofit plan. In order to decide on a rehabilitation and retrofit plan, information on thermal degradation of building materials and connections are vital. A critical knowledge gap exists in terms of...

Improving Fatigue Cracking and Moisture Resistance of Asphalt Mixtures

Creator:: Obaid, Ihsan A.
Abstract:: The resistance of asphalt concrete pavement to distresses such as fatigue cracking and permanent deformation is governed by how well the structure can resist loading under a variety of traffic and climate-related conditions. Asphalt binder type and content are typically the variables that pavement engineers can manipulate to render the...

Second nature : domestication as experiment and metaphor in 20th century American psychobiology

Creator:: Blanchard, Nicholas
Abstract:: By 1900 domestication was a promising, if somewhat vexed, subject in biology. Volumes had been written about domestication, but little serious scientific inquiry was directed toward the phenomenon. Expertise lay with practical men, primarily breeders and fanciers. The bulk of scientific commentary on domestication came from anthropologists who derived theories...

Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

Creator:: Senturk, Ahmet Ekin
Abstract:: Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

Creator:: McNeff, Patrick S.
Abstract:: Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...
