Embodiment approach 1
[0048] As a metal material, a test piece of 20 mm x 50 mm x 1.25 mm was cut out from an elongated material made of industrial pure aluminum (JIS alloy number: 1100) using a cutting machine with an outer circular cutting edge, and the surface of the test piece was quickly cleaned with ethanol.
[0049] Using an ultrasonic homogenizer as an ultrasonic application device, apply an appropriate amount of silicone grease to the end face of a titanium alloy horn with a diameter of 22mm, and then use a clamp to press the above-mentioned industrial pure aluminum elongated material test piece on the end face, and apply 19kHz and 300W Ultrasonic vibration for 60 seconds. This operation was repeated three times.
[0050] The test piece of the commercially pure aluminum elongated material to which ultrasonic waves have been applied is placed in a vacuum heating furnace, and heat-treated for 1 hour using a vacuum degree of 5 Pa and a heating temperature of 468K, that is, heating temperature...
Embodiment approach 2
[0055] As a metal material, a 20 mm × 50 mm × 1.25 mm test piece was cut out from an industrial pure iron cold-rolled material using a cutting machine with an outer circular cutting edge, and the surface of the test piece was quickly cleaned with ethanol.
[0056] Using an ultrasonic homogenizer as an ultrasonic application device, apply an appropriate amount of silicone grease to the end face of a titanium alloy horn with a diameter of 22mm, and then use a clamp to press the above-mentioned industrial pure iron cold-rolled material test piece on the end face, and apply 19kHz and 300W Ultrasonic vibration for 60 seconds.
[0057] Place the test piece of industrial pure iron cold-rolled material subjected to ultrasonic waves in a vacuum heating furnace, and use a vacuum degree of 5Pa and a heating temperature of 923K to perform heat treatment for 1 hour, that is, heating temperature / melting point=0.51.
[0058] Deformation and dimensional changes due to the above treatments wer...
Embodiment approach 3
[0062] As a metal material, a test piece of 20 mm x 50 mm x 1.25 mm was cut out from an elongated material made of AZ31 using a cutting machine having an outer circular cutting edge, and the surface of the test piece was quickly cleaned with ethanol.
[0063] Use an ultrasonic homogenizer as an ultrasonic application device, apply an appropriate amount of silicone grease to the end face of a titanium alloy horn with a diameter of 22mm, and then use a clamp to press the above-mentioned AZ31 elongated material specimen on the end face, and apply 19kHz and 200W ultrasonic vibration 15 seconds.
[0064] A test piece of an elongated material made of AZ31 to which ultrasonic waves have been applied is placed in a vacuum heating furnace, and heat-treated for 1 hour using a vacuum degree of 5 Pa and a heating temperature of 503K, that is, heating temperature / melting point=0.54.
[0065] In the test piece of the elongated material made of AZ31, almost no deformation and dimensional cha...
