Title
Research Paper - Materials Processing - : Fabrication of High Strength and High Electrical Conductivity Cu Alloys by Rod Milling
이기양Kee Yang Lee, 권숙인Sook In Kwun
Abstract
The mechanical properties and electrical conductivity of mechanically alloyed Cu alloys containing either Fe or Cr were investigated. The mechanical alloying process by rod milling was also compared with that by conventional ball milling. Rod milling needed less milling time to reach a steady state in mechanical alloying than ball milling. The grain size of the extruded bar after rod milling was as small as 200 ㎚. The Cu alloys produced by rod milling showed higher thermal stability and higher electrical conductivity than those produced by ball milling. The addition of either Fe or Cr as small as 1vol.% into Cu resulted in high tensile strength over 600MPa and the electrical conductivity of % IACS 68% and 74.5%, respectively.
