Grain refinement was carried out by two different modifiers: AlTi5B1 and Al3B. For each test, samples were cast before and after degassing of melt. Therefore, a new hot tearing tendency index was developed by both bifilm calculations and porosity that occurred in the middle of T-zone of casting parts. Results indicated that hot tearing of cast aluminum alloys was a complex phenomenon, and bifilms play a major role, especially by compensating for shrinkage and consequently contributing to the inconsistencies in results.eninfo:eu-repo/semantics/closedAccesscastingaluminum alloysgrain refiningsimulationhot tearingArticle10.1007/s40962-017-0197-9123589595WOS:000436927100018Q3Q2
