Effect of Initial Heat Treatment on DBTT of F82H Steel Irradiated by Neutrons
Fusion Science & Technology, 2005The dependence of ductile-brittle transition temperature (DBTT) on tempering time and temperature was examined for a martensitic steel F82H irradiated at 150 and 250°C to a neutron dose of 1.9 dpa ...

EFFECT OF THE PRECIPITATION OF Cu-RICH CLUSTERS ON THE DBTT OF RPV SIMULATED STEEL
Acta Metallurgica Sinica, 2012Reactor pressure vessels(RPVs) are usually made of low alloy ferritic steels,among which A508-Ⅲsteel is a typical one.The long-term neutron irradiation can induce the embrittlement of RPV steels,and the embrittlement may lead to a reduction of the RPV service life.Generally, this behavior of the embrittlement is well established and is typically ...

Effect of small additional elements on DBTT of V–4Cr–4Ti irradiated at low temperatures
Journal of Nuclear Materials, 1998Abstract As a part of a program to screen several V–4Cr–4Ti containing Si, Al and Y alloys and optimize the amounts of Si, Al and Y, the Charpy impact test of five kinds of V–4Cr–4Ti–Si–Al–Y alloys by an instrumented Charpy impact testing machine using miniaturized specimens (1.5 mm × 1.5 mm × 20 mm) have been conducted before and after neutron ...

Volume 3: Design and Analysis, 2016
In this paper, we demonstrate that a deterministic approach requiring only tensile test data for different temperatures has a possibility to predict the minimum fracture toughness for these temperatures. The material is assumed to be in the Ductile-to-Brittle-Transition Temperature (DBTT) region.

Journal of Pressure Vessel Technology, 2009
The fracture behavior of pipes with penetrating cracks was experimentally investigated with the results of the load-deflection curves and crack length. J-R curves were obtained from the testing results for different temperatures. With the decrement in temperature, the critical J integral decreases and the tearing modulus increases. An updated continuum

Engineering Failure Analysis, 2011
Abstract Safety analysis of critical components and the overall plant is a major and important task in the field of mechanical engineering. Therefore, it is essential to know the allowable loads and the corresponding failure behaviour (e.g., crack initiation, growth and instability) of the component.
