s: The semi-solid slurry of Al-25%Si hypereutectic aluminum alloy was prepared through a copper serpentine pouring channel, the effect temperature and numbers channel bend on microstructure investigated. results show that primary silicon grains in solidified at traditional condition are very large average grain size is about 65.3μm, however, when liquid poured fined obviously. If has three bends 747°C,the 33.7μm. four 747°C, 30.9μm. seven 28.6μm. analysis shows chilling inner wall...
In order to study the possibility of refining primary silicon grains in microstructure hypereutectic Al-Si alloy through a serpentine pouring channel, semi-solid slurry A390 aluminum was prepared water-cooled copper which is new method proposed recently for forming process, and effect temperature on investigated. The results show that with refined can be under given conditions especially when temperatures 690°C, obviously, equivalent grain size 19.7mm average shape factor about 0.7. analysis...
In the field of higher education, how to rely on big data technology better serve academic guidance college students has become an important part current talent training work in colleges and universities. Based technology, this paper builds accurate model for based portrait analysis. By collecting resource data, establishing label system, system development, practical application carrying out effectiveness test, it provides reference accurately guiding students' development helps high-quality
