Strength And Ductility

A Ti/Ti-based-metallic-glass interpenetrating phase composite (IPC) was prepared by infiltrating theTi34.3Zr31.5Ni5.5Cu5Be23.7melt into the porous Ti skeleton. Porous Ti limits the shear band (SB) propagation and promotes the SB multiplication, leading to the improved ductility. Moreover, the interpenetrating phase structure shows a mutual reinforcement effect for both amorphous and crystalline phases, making IPC possess higher strength than that calculated by the models held for the conventional composites. This finding will suggest a new way for preparing composites with high strength and ductility.

Bulk metallic glass (BMG) exhibits remarkable properties such as high strength, good stiffness and good corrosion resistance. However, the wear resistance of amorphous metals is not excellent as expected their high strength. It is thought that large local shear bands easily change into cracks for debris formation. The effective obstruction of shear band formation might be applied to improve the wear resistance of BMG. In this study, we tried to suppress shear band deformation by fine crystalline phase dispersion formed by semi-conductor laser irradiation. The microstructures of irradiated Zr-based BMG specimens were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The fine dispersions of crystalline phases are observed in the amorphous matrix. The optimum condition for laser irradiation was discussed.

Abstract METGLAS MBF-30A is a brazing foil in ductile, flexible metallic-glass form (a similar grade, MBF-30, is identical except that it has larger dimensional tolerances). This foil provides an alloy with high strength at both elevated and room temperatures. It can be used to join highly stressed stainless steel and heat-resisting alloy components. The excellent flow characteristics of this alloy recommend it for assemblies with good fit-up and tight-tolerance joints. It works well on thin-foil, honeycomb designs and on fairly heavy components. This datasheet provides information on composition, physical properties, and microstructure. It also includes information on heat treating. Filing Code: Ni-273.
