摘要

Metallic glasses exhibit low viscosity in a temperature range between the glass-transition and the crystallization temperature which allows successful sintering of glassy powders. Microwave (MW) heating being a volumetric heating has significant advantages over conventional heating in materials processing, such as substantial energy savings, rapid heating rates and process cleanness. In the present study we investigate the stability of the Fe_(73)Si_7B_(17)Nb_3, Fe_(65)Co_(10)Ga_5P_(12)C_4B_4, Ni_(52.5)Zr_(15)Nb_(10)Ti_(15)Pt_(7.5), Zr_(55)Cu_(30)Al_(10)Ni_5 and Ti_(47.5)Zr_(10)Cu_(30)Pd_(7.5)Sn_5 glassy powders and the formation of the bulk metallic glassy samples by microwave heating in a single mode cavity with separate electric (E) and magnetic (H) filed maxima in an inert atmosphere (Ar). This work represents a new field - microwave radiation-assisted heating and sintering of glassy samples.
