PCT No. PCT/AU95/00372 Sec. 371 Date Dec. 20, 1996 Sec. 102(e) Date Dec. 20, 1996 PCT Filed Jun. 23, 1995 PCT Pub. No. WO96/00449 PCT Pub. Date Jan. 4, 1996A method of bonding together metallic glass laminations to form a stack and thereafter shaping the stack, for example, by cutting, to form a bulk object such as a wound stator or rotor of an electric motor. Metallic glass is an amorphous ferromagnetic material used in the construction of electrical equipment to reduce core losses. The method involves coating individual laminations of metallic glass with a temperature resistant, non-gas producing metal bonding agent, stacking the coated laminations, applying a pressure to the stacked laminations such that the bonding agent does not exude from between the laminations, allowing the bonding agent to cure, and thereafter shaping the stacked laminations as required. In some cases, temperature resistant wiring and insulation are fitted to the shaped laminations and heated to a temperature sufficient to anneal the metallic glass. The laminations are shaped by cutting with a mixture of fluent material and abrasive material emitted from a nozzle at high pressure. The laminations or the nozzle are adjustable such that the outer surface of the cutting mixture is perpendicular to the plane of the surface of the laminations. The method can be employed for manufacturing other products, such as transformers, which can advantageously employ the ferromagnetic properties of metallic glass.
