Macrotexture Map Visualizing Texture Heterogeneity in Polycrystalline Parts

Номер: US20190353602A1
Автор: Li Dongsheng
Принадлежит: Advanced Manufacturing LLC

This invention provides a method, system, and computer program to visualize texture (crystal orientation distribution) heterogeneity in polycrystalline aggregate part in large length scale. This is a critical representation step for microstructure characterization, useful in effective behavior simulation, risk analysis and hotspot identification. In contrast to orientation image map where each color component represents a crystal orientation, each color in this macrotexture map represents a set of texture. Different color represent different texture and similar texture shall have similar color. This method will provide a critical tool in evaluating texture heterogeneity of components, leading to a first-hand understanding of property heterogeneity and anisotropy. For an experienced user, these maps serve the same purpose in identifying high risk locations in the investigated component as medical imaging maps do for diagnosis purpose. This method will also serve as a starting point in mesoscale simulation with meshing sensitivity based on the texture heterogeneity. It will provide a bridge between texture characterization and behavior simulation of component with texture heterogeneity. This method will also offer a linkage between crystal plasticity simulation in small length scale and finite element/difference simulation in large length scale. 1.

Production of perforated two-dimensional materials with holes of a desired size range, a narrow size distribution, and a high and uniform density remains a challenge, at least partially, due to physical and chemical inconsistencies from sheet-to-sheet of the two-dimensional material and surface contamination. This disclosure describes methods for monitoring and adjusting perforation or healing conditions in real-time to address inter- and intra-sheet variability. In situ or substantially simultaneous feedback on defect production or healing may be provided either locally or globally on a graphene or other two-dimensional sheet. The feedback data can be used to adjust perforation or healing parameters, such as the total dose or efficacy of the perforating radiation, to achieve the desired defect state.

Methods of determining the mineralogy of calcined and flux-calcined diatomite

Номер: US10908102B2
Принадлежит: EP Minerals LLC

A method of determining opal-C and cristobalite contents of a product that comprises diatomite is disclosed. The method may comprise performing thermal processing to determine a loss on ignition for a representative first portion of a sample of the product; identifying and quantifying primary and secondary peaks present in a first diffraction pattern that results from bulk powder X-ray Diffraction on a representative second portion of the sample; and using a known standard sample of cristobalite to determine whether the primary and secondary peaks present in the first diffraction pattern indicate the presence of opal-C or cristobalite in the product.

Opaline flux-calcined diatomite products

Номер: US11243177B2
Принадлежит: EP Minerals LLC

A diatomite product and method of using such is disclosed. The diatomite product may comprise sodium flux-calcined diatomite, wherein the diatomite product has a crystalline silica content of less than about 1 wt %, and the diatomite product has a permeability between 0.8 darcy and about 30 darcy. In some embodiments, the diatomite product may be in particulate or powdered form. This disclosure also concerns flux-calcined silica products containing low or non-detectable levels of crystalline silica. Some of these products can be further characterized by high permeabilities and a measurable content of opal-C, a hydrated form of silicon dioxide.

Methods for in situ monitoring and control of defect formation or healing

Номер: WO2017180133A1
Принадлежит: LOCKHEED MARTIN CORPORATION

Production of perforated two-dimensional materials with holes of a desired size range, a narrow size distribution, and a high and uniform density remains a challenge, at least partially, due to physical and chemical inconsistencies from sheet-to-sheet of the two-dimensional material and surface contamination. This disclosure describes methods for monitoring and adjusting perforation or healing conditions in real-time to address inter- and intra-sheet variability. In situ or substantially simultaneous feedback on defect production or healing may be provided either locally or globally on a graphene or other two-dimensional sheet. The feedback data can be used to adjust perforation or healing parameters, such as the total dose or efficacy of the perforating radiation, to achieve the desired defect state.
