Abstract: Analytical life prediction methods are being developed for high-temperature turbine and valve studs/bolts. In order to validate the approach, the calculated results are compared to the results ...

Abstract: This paper presents a historical review of the assessment of remaining creep life for components operating under stress at elevated temperatures. Topics considered in this review include the ...

Abstract: The concept of mechanical equation of state is reviewed based on experimental results on 1100 aluminum alloy. It is applied to describe the effects of cold work on creep and creep rupture ...

Abstract: A research project was conducted to develop and validate an improved, analytical life prediction method for high-temperature turbine and valve studs/bolts. The life prediction method used the ...

Abstract: This paper describes an investigation of the tensile and creep properties of annealed 9 Cr-1 Mo steel. Tensile tests were conducted at temperatures from 70 to 1050 F while creep tests were ...

Abstract: An investigation was performed on a circumferential weld joint in a 1/2 Cr-1/2 Mo-1/4 V high-pressure steam inlet pipe following the detection of steam leakage in a weld area. The component, ...
