| Popis: | The successful use of a cobalt-based metallic glass in joining molybdenum disilicide (MoSi2) to stainless steel 316L was demonstrated. The cobalt-based metallic glass (METGLAS™ (Allied Signal Inc., Parsippany, NJ) 2714A) was found to wet the MoSi2 and stainless steel surfaces and provide high-quality joints. The joining was completed at 1050 °C for 60 min. Postbrazing metallographic evaluations coupled with quantitative elemental analysis indicated the presence of a Co-Cr-Si ternary phase with CoSi and CoSi2 precipitates within the braze. Brazing conducted under these process parameters was found to provide interfacial joint strengths in the range of 60 to 80 MPa. |
