Title
Metal Fiber Production by Powder Extrusion Method
김동익Dong Ik Kim, 김성균Seong Gyoon Kim, 최회진Hoe Jin Choi
Abstract
A new process for the metal fiber production by the powder extrusion has been developed. Being compared with the conventional processes, such as the bundle drawing method, the shatter machining method and the in-rotating water melt spinning method, the process has two distinctive advantages. One is that the fibers having a diameter below l0㎛ can be easily manufactured, the other is that the diameter, the length and the cross-sectional shape of the fibers can be controlled easily by the selection of the diameter of initial metal powders, extrusion ratios and extrusion die shapes. The silver fibers of 2㎛ wide and 30㎛ long and aluminum fibers of 5-10㎛ wide 1-3㎜ long were demonstrated.
