The effects of metalloids Si(4-27 at%) and B(5-22 at%) on the structure and magnetic properties of melt spun cobalt based alloys containing 5at% Fe have been studied. XRD results revealed that in non-eutectic ternary CoFeSi and CoFeB alloys, the additions of Si or B, alone can not lead to full amorphization of melt spun ribbons. In quaternary CoFeSiB alloys, the total amounts of Si and B additi...

A lower vacuum housing (34) of a sensor dewar (26) is fabricated in a single brazing operation from ceramic and metallic components. The components are assembled with ceramic-to-metal interfaces and metal-to-metal interfaces. Brazing is accomplished by active brazing of the ceramic­ to-metal interfaces and non-active brazing of the metal-to­ metal interfaces. Specific combinations of active bra...

Magnesium (Mg) based alloys are the most advanced cardiovascular stent materials. This new generation of stent scaffold is currently under clinical evaluation with encouraging outcomes. All these Mg alloys contain a certain amount of rare earth (RE) elements though the exact composition is not yet disclosed. RE alloying can usually enhance the mechanical strength of different metal alloys but t...
