The finite element method has been widely used in property simulations and the design of cemented carbides, but most have focused on individual properties alloy, few studies were done multiple to explore micromechanical simultaneously. In this work, a model is established based real microstructure from scanning electron microscopy images carbide, elastoplastic are imparted both WC Co phases. residual thermal stress, fracture toughness, hardness WC-10 wt.%Co carbide subject different external...
It is of great academic and engineering application to study the evolution microstructure properties age-strengthened aluminum alloys during heat treatment establish quantitative prediction models that can be applied industrial production. The main factors affecting peak aging state strength are precipitates, solid solution elements, grain size effects, textures formed material processing. In this work, these multi-scale integrated into framework knowledge graph assist following crystal...
As a new type of high-performance material, gradient structural steel is widely used in engineering fields due to its unique microstructure and excellent mechanical properties. For the prevalent fatigue failure problem, rate change local grain size gradients along structure (referred as rate) key parameter design structures, which significantly affects performance steel. In this work, method ‘Voronoi primary + secondary modeling’ adopted successfully establish three typical high-strength...
Purpose During the forming process, aluminum alloy sheets develop various types of textures and are subjected to cyclic loading as structural components, resulting in fatigue damage. This study aims polycrystalline models with different orientation distributions incorporate suitable indicator parameters investigate effect distribution on mechanical properties Al-7.02Mg-1.78Zn alloys under loading. Design/methodology/approach In this study, a two-dimensional model 150 equiaxed grains was...
The airport is an important infrastructure for the development of civil aviation industry, and whether site selection reasonable or not determines operation even whole transport network. With airports routes increase rapidly, which makes airspace become one main limiting factors selection. First, this paper collects geographic information complex area uses Supermap software to build spatial database; then, according methods, analyzes structure area, vectors based on database, selecting...

Age-strengthened aluminum alloys as important structural lightweight materials have much lower fatigue properties than conventional steel. This study focuses on the effect of precipitation-free zone (PFZ) mechanical age-strengthened alloys. A polycrystalline model containing PFZ was created by secondary development traditional and combined with crystal plasticity finite element method to simulate stress-strain response local plastic deformation behaviors under different microstructures. The...
Age-strengthened aluminum alloys, as important lightweight structural materials, have significantly lower fatigue properties compared to non-age-strengthened alloys. In this study, the polycrystalline models containing precipitation-free zones (PFZ) were constructed by secondary development of traditional model modifying mesh file. Polycrystalline finite element simulations peak age-treated Al-7.02Mg-1.98Zn alloys carried out with model. The results demonstrate that PFZ’s presence markedly...
