However, it has almost always been neglected in the previous numerical simulation works. To investigate the effects of the mushy zone on the temperature and the melt flow fields during the crystal growth, the GaInSb crystal growth process with the traveling heater method (THM) was numerically simulated. The results indicate that the mushy zone significantly affects the height of the melting zone (HM), the curvature of the growth interface (δR), the axial temperature gradient at the growth solid-liquid interface front, and the flow velocity of the melt in the melting zone during the crystal growth process. As the phase transition temperature interval (ΔT, the temperature difference between the liquidus and solidus in the pseudo-binary phase diagram) increased from 0 K to 1 K, the HM increased by 3.01%, the δR increased by 80.86%, the axial temperature gradient at the growth interface front increased by 111.11%, and the maximum velocity of the melt in the melting zone decreased by 5.05%; as the ΔT increased from 1 K to 7 K, the HM increased by 33.91%, the axial temperature gradient at the growth interface front increased by 42.11%, and the δR decreased by 37.31%; the maximum velocity of the melt in the melting zone decreased by 10.64%.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 1","pages":"353 - 376"},"PeriodicalIF":2.1,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversely, 3D printing technology offers high-precision manufacturing, customizable mass production, shorter production cycles, and ease of producing complex structures, effectively addressing the shortcomings of conventional microreactor fabrication methods. This paper reviews the application of 3D printing technology in manufacturing microreactors based on existing literature, focusing on the technical processes of 3D printing, applications of 3D printed microreactors, selection of 3D printing materials, and performance analysis.

Improving the surface quality of ZnSe is an important way to expand its application range. The anisotropy of ZnSe crystals affects the surface quality after material removal. Through the nano-indentation experiment of ZnSe crystals, the anisotropy hardness were observed. The deformation behavior and property differences of materials in different directions has been revealed by molecular dynamics simulation. ZnSe nanofilm plastic deformation is primarily controlled by 1/2 <110 > -type dislocation nucleation and expansion, as per simulation results. The generated dislocation loops during the indentation process exhibit a strong correlation with the applied load. Dislocation slip is generated on all three crystalline planes of the simulation, and the main slip system is {111} <110 >. The (111) crystalline plane has the lowest hardness, and the (100) crystalline plane has the lowest Young’s modulus. The simulation and experimental results show clear anisotropy in hardness, Young’s modulus, elastic modulus, initial plasticity, and elastic recovery rate.

In this paper, novel solutions coupling physical mechanisms into the machine learning modeling are proposed, and their feasibility has been fully demonstrated by analyzing experimental verification and industrial trial production. By comparison with experimental data, the results show that the proposed model accurately describes the microstructure evolution during hot rolling and cooling under complex processing conditions. On this basis, the flexible cooling system is developed by multi-objective particle swarm optimization. Compared with the traditional purely data-driven optimization method, results show that the proposed model ensures that the optimization results meet the requirements of multiple property indicator collaborative optimization but also obtain the optimal comprehensive property and quality stability by controlling the cooling path. Finally, the established system applied to guide the industrial production of steel and the potential for matching optimum cooling parameters according to the fluctuation in steel composition and rolling parameters to achieve a compensatory effect is proved through metallographic observations of final microstructures under different cooling paths.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 1","pages":"91 - 105"},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
