PURPOSE:To join securely amorphous alloys to each other or to various metals while maintaining the amorphous structure by applying ultrasonic oscillation to the joint surfaces of the metallic materials one of which consists of the amorphous alloy under the pressure. CONSTITUTION:Amorphous alloys or said alloy and the other metallic material (blank joint material) 1, 2 are superposed and are grasped by an oscillating bar 3 and an anvil 4. Ultrasonic oscillation is transmitted from a magnetostrictive oscillator 6 via a transducer 7 to the bar 3 to join the blank materials 1, 2 under the pressurization by a pressure P. A tip 5 is used after the same is properly exchanged with a knurled, smooth or other chips according to the materials 1, 2. If the pressure P is increased, the optimum time for applying the ultrasonic wave decreases and said time is preferably about <=3sec. The secure joint at least one of which is the amorphous alloy is obtd. while the amorphous structure is maintained by the above-mentioned method. |
