Abstract
Fe-Ni alloys were prepared by electrodeposition process assisted with mechanical polishing and analyzed by comparison with the traditional electrodeposition process. The results showed that mechanical polishing can significantly affect the crystalline growth and grain refinement resulted.
Simultaneously the polishing can significantly enhance the micro-hardness and reduce the thermal expansion coefficient (TEC) of the electrodeposited Fe-Ni alloy. Both micro-hardness and thermal expansion coefficient decrease with increase of current density due to the grain coarsen. A promising
technology for achieving Fe-Ni alloy with low TEC and high strength can be expected.
