Claim:
1. A method of forming a hermetic seal between a first part and a second part, comprising: locally heating a first surface of a first part and a second surface of a second part to a first temperature below a first softening temperature of the first part and below a second softening temperature of the second part, wherein the operation of locally heating the first surface of the first part and the second surface of the second part comprises heating, to the first temperature, only to a depth of 1 mm or less below the first and second surfaces, thereby forming heated first and second surfaces; positioning an amorphous alloy having a crystallization temperature Tx greater than the first temperature and a glass transition temperature Tg less than the first temperature in contact with the first and the second heated surfaces, thereby heating the amorphous alloy above Tg, wherein the amorphous alloy is preheated to a second temperature above an ambient temperature and less than Tg prior to being placed in contact with the heated first and second surfaces; and cooling the amorphous alloy to a third temperature below Tg, thereby forming a hermetic seal between the first surface and the second surface.
