Title:
METHOD FOR MANUFACTURING LIGHTWEIGHT COMPOSITE MATERIAL COMPRISING STAINLESS STEEL AND ALUMINIUM OR ALLOYS THEREOF, AND LIGHTWEIGHT COMPOSITE MATERIAL PREPARED BY SAME
Document Type and Number:
WIPO Patent Application WO/2017/119790
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a lightweight stainless steel-aluminum alloy composite material, the method comprising the steps of: (a) manufacturing a mixture powder by milling stainless steel powder and aluminum powder; and (b) performing spark plasma sintering (SPS) on the mixture powder prepared in step (a). According to the present invention, the method for manufacturing a lightweight stainless steel-aluminum composite material quickly densifies and complexes the stainless steel powder and the aluminum alloy powder, which are starting materials, without changing the composition thereof by using an SPS process in a complexation step, thereby enabling the composite material having excellent material properties including all of the original advantages (lightweight properties and excellent corrosion resistance/workability/mechanical properties) of each starting raw material to be manufactured. In addition, since the SPS process is used for the complexation of raw material powder, the composite material having excellent material properties, optimized in an application field of the composite material, can be economically and easily manufactured through the control of a mixing weight ratio of the stainless steel powder and the aluminum powder, and the like.
