Mo-Si-B Alloy Development
Alloys consisting of the phases α-Mo (Mo solid solution), Mo3Si, and Mo5SiB2 (“T2”) were fabricated by ingot and powder metallurgy. A novel powder-metallurgical processing technique was developed which allows the fabrication of silicide alloys with a continuous α-Mo matrix. In these alloys the relatively ductile and tough α-Mo matrix acts as a “binder” for brittle silicide particles. An alloy p...
متن کاملImproving of Microstructure and Mechanical Properties of Al-A356 Alloy with Compo-Casting Method
Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...
متن کاملOptimization of Microstructure and Mechanical Properties of Al-A360 Produced by Semi-Solid Casting
Semi-Solid Casting (SSM) is a new process that could produce globular structures with mechanical properties. The cooling slope method (CLM) is a one of this process that was employed to produce the A360 feedstock. In this method, The dendritic primary phase in the conventionally cast A356 alloy has transformed into a non-dendritic one. In this paper, The molten alloy with the temperature (PT) o...
متن کاملRole of Microstructure in Promoting Fracture and Fatigue Resistance in Mo-Si-B Alloys
An investigation of how microstructural features affect the fracture and fatigue properties of a promising class of high temperature Mo-Si-B based alloys is presented. Fracture toughness and fatigue-crack growth properties are measured at 25o and 1300oC for five Mo-Mo3Si-Mo5SiB2 containing alloys produced by powder metallurgy with α-Mo matrices. Results are compared with previous studies on int...
متن کاملAmbient- to Elevated-Temperature Fracture and Fatigue Properties of Mo-Si-B Alloys: Role of Microstructure
Ambientto elevated-temperature fracture and fatigue-crack growth results are presented for five MoMo3Si-Mo5SiB2–containing -Mo matrix (17 to 49 vol pct) alloys, which are compared to results for intermetallic-matrix alloys with similar compositions. By increasing the -Mo volume fraction, ductility, or microstructural coarseness, or by using a continuous -Mo matrix, it was found that improved fr...
