Abstract: The master curve reference temperature, T0, characterizes the fracture performance of structural steels in the ductiletobrittle transition region. For a given material, this reference temperature is estimated via fracture ...

Abstract: The simplified model test (SMT) method is an alternate approach to determine the cyclic life at elevated temperature. It is based on the use of creep–fatigue hold time test data from test specimens with elastic followup ...

Abstract: A twobar thermal ratcheting procedure has been implemented to Alloy 617 at very high temperatures. The procedure is based on two bars tested on two coupled servo hydraulic machines to achieve equal displacement and constant ...

Abstract: This is Part II of a study on twobar thermal ratcheting for Alloy 617. The ratcheting strains were evaluated for conditions with the same temperature range but with different mean stresses, heating and cooling rates, time ...

Abstract: Use of corrosion-resistant cladding can greatly extend the design life of structural components in many advanced reactor systems. However, there are currently no ASME design rules for cladded components to guard against ...

Abstract: This technical note describes a minimum creep rate model for 2-1/4Cr-1Mo steel that is consistent with the current creep strain equation embedded in the ASME Boiler & Pressure Vessel Code Section III, Division 5, ...

Abstract: The challenge of using existing ASME Section III, Division 5, class A metallic materials for the construction of structural components of advanced reactors with corrosive coolants could be mitigated by allowing designers ...

Abstract: Even with its small size, the Gurney flap (GF) can help considerably in increasing the lift of foils and wings. To exploit this feature, the objective of this research was to numerically study the effects of this flow ...
