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 ...

Reduction method of DBTT shift due to irradiation for reduced-activation ferritic/martensitic steels
Journal of Nuclear Materials, 2010Abstract The method for reducing irradiation-induced DBTT shift of reduced-activation ferritic/martensitic steels was examined. F82H-LN (low nitrogen, 20 ppm), F82H+60 ppm11B+200 ppmN and F82H+60 ppm10B+200 ppmN steels tempered at 780 °C for 0.5 h were irradiated at 250 °C to 2 dpa, and the results for Charpy impact tests were analyzed.

A method has been suggested to accurately determine the DBTT of diffusion aluminide bond coats. Micro-tensile testing of free-standing coating samples has been carried out. The DBTT was determined based on the variation of plastic strain-to-fracture with temperature.

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.

Integrity of structures in various technologies depend on the fracture behaviors of materials, and in general the fracture characteristics of s tructural m aterials are evaluated using destructive tests, such as Charpy, fracture toughness, and other such techniques.

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.
