Synthesis of bulk amorphous alloy and composites by warm rolling process

摘要

We report the fabrication of monolithic bulk amorphous Ni_(59)Zr_(20)Ti_(16)Si_2Sn_3 alloy and amorphous Ni_(59)Zr_(20)Ti_(16)Si_2Sn_3 alloy reinforced Cu matrix composite using a combination of RCRF (Repeated Cold Rolling and Folding) and warm rolling processes. Based on the TTT curve established for the amorphous Ni_(59)Zr_(20)Ti_(16)Si_2Sn_3 alloy, the crystallization of the amorphous ribbon is prevented during warm rolling process. The micro-hardness of the amorphous alloy (600130 Hv) is comparable with those for other Ni-based amorphous alloys.
