Embrittlement and Flow Localization of Reactor Structural Materials
Notch effects have been analyzed utilizing finite element method (FEM) and EBSD misorientation map for unirradiated and irradiated 316L stainless steel. The major issue of interest is the possibility that low ductility, often found following irradiation exposure, will translate into low notch …

Evaluation of Temper Embrittlement in 2.25 Cr- 1 Mo Weld Metals Utilizing X-Ray Diffraction.
… of this type of embrittlement are a reduction in notch toughness, an increase in the ductile-to-brittle transition temperature as measured by Charpy vee-notch impact tests, and a change in fracture mode from ductile transgranular to brittle intergranular.

Mechanical and microstructural properties of ultra-low carbon bainitic steel weld metal
… power and cover gas. The strength and Charpy V-notch toughness of the resulting welds was investigated. It was found that the GTA weld using 100% argon cover gas had excellent toughness (well above Navy requirements), but the strength was at the minimum specification. The GMA welds using a cover …

Development of Stage-I tempered high strength cast steel for ground engaging tools
… oxygen melt practice gave 35% improvement in notch toughness. A Mn-Si-Mo-V steel was formulated to minimize solidification shrinkage porosity. Steels were heat treated to a lath martensitic microstructure, and a Stage-I tempered hardness of 53-55 HRC. Yield strength and ultimate tensile …

Fracture in polycrystalline diamond. Investigating cracking and toughness behaviour using a miniature double torsion technique
… The extremely high stiffness and relatively low toughness of the PCD material make controllable crack propagation and fracture parameter studies very difficult. Therefore, the research project investigated the ability of the DT technique to controllably initiate and propagate cracks, followed by …
