Dynamics of superstructure formation in intermetallic compounds

WebApr 12, 2024 · The relevant research shows that the formation of ordered intermetallics from the salts precursors during thermal treatment is rely on the preformed alloys [34], although the phase transition from random alloy into the intermetallics could be happened under a milder temperature. WebMany ordered intermetallic alloys have attractive high-temperature properties; however, low ductility and brittle fracture limit their use for structural applications. The embrittlement in these alloys is mainly caused by an insufficient number of slip systems (bulk brittleness) and poor grain-boundary cohesion.
