摘要:
A joined parts of Ni-Ti alloys with different metals having a joined interfacial parts of Ni-Ti alloys with different metals other than said alloy, comprising a melt forged structure obtained through the reactive fusion due to the fusion of at least one metal bordering on said joined interface and the application of pressure, and a hot forged structure of Ni-Ti alloys obtained by softening said alloy at high temperature and applying pressure on the side of Ni-Ti alloys and a hot forged structure of said different metals obtained by softening said metal at high temperature and applying pressure on the side of different metals across said melt forged structure, and a direct joining method for obtaining this joined parts are disclosed. It is possible to join Ni-Ti alloys component with different metals component providing high strength without deteriorating the characteristics.
摘要:
A Ni-Ti superelastic alloy demonstrates superelastic properties at normal temperatures from about 0 and 30°C. The superelastic alloy allows shape alteration when the temperature is in excess of 40°C. The Ni-Ti superelastic alloy is produced by plastic working a composition containing essentially Ni and Ti, and subjecting the composition to heat treatment at a temperature between 600 and 800°C to impart shape memory. When the Ni-Ti superelastic alloy is used in an eyeglass frame, it allows the shape of the pad arms to be adjusted at temperatures above about 40°C.
