ABSTRACT A methodology is proposed in this paper to compute local probability of fracture a representative volume element from microstructural and fractographic information. microscale approach reported for cleavage modelling bainitic reactor pressure vessel steel. fine metallographic micro‐mechanical characterization has been performed. Morphological information used generate realistic three‐dimensional (3D) aggregates suitable calibration process set up identify an accurate crystal...
Kossel microdiffraction in a scanning electron microscope enables determination of local elastic strains. With patterns recorded by CCD camera and some automation the strain process, this technique may become convenient tool for analysis As all methods, critical applicability is its resolution. The resolution was estimated number ways: from simplest tests based on simulated (of an Ni alloy), through sharp experimental Ge, to estimates obtained situ tensile straining single crystals Ni-based...
The Kossel microdiffraction in a scanning electron microscope allows for local stress determination. This technique has been applied to monitor evolution within grains of austenite the course martensitic transformation shape memory alloy. diffraction patterns were recorded during situ tensile straining Cu-Al-Be These innovative measurements show large heterogeneities between grains, with ratio exceeding two. As martensite variants are stress-induced, shear components appear individual austenite.
