Abstract:
A method for consolidating a pre-form made of powder, comprising: (a) placing the pre-form between smart susceptors; (b) heating the smart susceptors to a leveling temperature by applying a varying low-strength magnetic field having a magnetic flux that passes through surfaces of the smart susceptors; (c) applying consolidation pressure to the pre-form at least during a time period subsequent to the temperature of the smart susceptors reaching the leveling temperature; and (d) while consolidation pressure is being applied, applying a pulsed high-strength magnetic field having a magnetic flux that passes through a surface of the pre-form. The strength and pulse rate of the high-strength magnetic field are selected so that the crystallographic phase of the pre-form will rapidly oscillate at a substantially constant temperature. The pulsed high-strength magnetic field is applied sufficiently long that superplasticity of the pre-form is attained during phase oscillation.
