摘要:
In production of a Ti-base materal for eyeglass-frames of a core and sheath construction by cladding, a combination of Ti or Ti-base alloy for the core and Ni or Ni-base alloy for the sheath effectively prevents formation of fragile intermetallic compounds at the border, thereby greatly increasing the brazing strength of the product for advantageous use as eyeglass-frame parts.
