...; Elastic follow-up; Life prediction; High temperature; low strain range; hold time 1. INTRODUCTION Alloy 617 (UNS N06617), as a high-temperature nickelbased structural material, has been approved for elevated temperature service construction of Class A components because of its good mechanical performance...

... Ridge National Laboratory, Oak Ridge, Tennessee, USA 3Idaho National Laboratory, Idaho Falls, Idaho, USA ABSTRACT High-temperature reactor structural components are often under the complex multiaxial creep-fatigue (CF) loading conditions throughout the lifetime because of geometric and/or metallurgical...

... Abstract ASME Code Section III Division 5 (high temperature) primarily focuses on component design, with limited guidelines for piping analysis and design. Prior research has examined the analysis requirements of ASME Section III Divisions 1 and 5 with regard to piping analysis, and has...

... Abstract Both spiral-wound and kammprofile gaskets are used extensively at high temperature applications such as refineries, petrochemical plants, power plants, etc. In recent years, the use of kammprofile gaskets have seemed to gain momentum over the conventional spiral-wound gaskets. Since...

... Abstract In the published standards, selection criteria for bolt materials for high temperature and high pressure environments (exceeding 540°C (1000°F) and 300 lb) has not been specified. In addition, it seems that there are few studies that summarize how the initial bolt load and the flange...

... calculation or FEA (Design by Analysis). In most cases the time dependent material properties are not considered, as the high temperature effects are minor. In this paper the author will focus on the high temperature applications, where time dependent material and flange properties need to be addressed. Shown...

... Abstract The structural integrity of reactor components is very essential for the reliable operation of all types of power plants, especially for components operating at elevated temperature where creep effects are significant and where components are subjected to high-temperature alteration...

.... Included in these new nuclear technology are small modular Generation VI reactors, referred to as Advanced Modular Reactors (AMRs). It has previously been identified that there is currently no clear route to demonstrating the structural integrity of such high temperature reactors to the UK regulator...

.... As the application possibilities for these repairs expand, higher service temperatures have become a focus for both repair manufacturers and operators. High temperatures (> 250°F) have a number of impacts on polymer composites, including reducing the elastic modulus of the repair material, which tends to reduce...

..., and moisture have been under investigation by many researchers. The major objective of this study is to evaluate the effects of harsh environment (e.g. seawater and high temperature) on the structural properties of E-glass epoxy composite materials. These effects were studied in terms of seawater absorption...
