Synthesis techniques include hot extrusion, hot isostatic pressing, spark plasma sintering and friction consolidation. The effects of process parameters on the resulting microstructures and performance are discussed for each technique. Average oxide size, average grain size, and porosity are compared across techniques, as well as mechanical strength and ductility. Across consolidation techniques where temperature can be controlled, a low sintering temperature with a high sintering pressure is favorable for keeping oxide sizes, grain sizes, and porosity low. The use of yttrium and titanium for oxide formation has been evidenced to reduce oxide sizes, and tungsten additions have been shown to improve strength. Current literature suggests that the more mature hot extrusion technique produces stronger steel with consistently fine oxides, while other alternative solid-state consolidation, while promising, offer margin for improvement.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 11","pages":"6252 - 6276"},"PeriodicalIF":2.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142453110","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}

Reducing defects enhances electronic properties, decreasing device failures and increasing yields. A new algorithm is suggested in this study via computational modeling and simulation to ascertain the pulling speed necessary for silicon crystal growth with fewer defects. This algorithm can adjust the pulling speed dynamically to correctly position the boundary between vacancies and interstitials and allow enough recombination time during crystal growth before point defects reach the bulk defects nucleation temperature. Experimental validation is performed using polished silicon wafers taken from final silicon ingots, accompanied by laser particle count measurements. The results validate the effectiveness of the new algorithm in reducing defect formation during crystal growth. Furthermore, a comprehensive analysis of production speed, cost, and power consumption at different pulling speeds is provided. The suggested algorithm finds a middle ground between production efficiency and crystal quality, offering speed and cost optimization while maintaining minimal defect formation.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"76 11","pages":"6545 - 6554"},"PeriodicalIF":2.1,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142452922","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}

To manufacture the sample, first, a mixed suspension of g-C3N4 and TiB2 powders with a mass ratio of 1–10 was prepared in 96% ethanol. Then, the particles of the secondary phase were properly distributed in the main matrix with an ultrasonic stirrer. The SPS step was performed at 1900°C for 7 min with an external load of 40 MPa. In the following, SEM images and XRD patterns were used to investigate the microstructural development and phase analysis of the manufactured composite sample. Also, for phase studies, HSC Chemistry software was employed to identify the possible reactions according to thermodynamics principles. The results showed that the use of g-C3N4 as an additive in the TiB2-based composite resulted in a sample with lower relative density in such a way that the relative density decreased to 91.3% compared to the TiB2 monolithic sample with a relative density of 96.7%.
