Microstructure and Arc Erosion Characteristics ofAg/Ni Contacts by Mechanical Alloying
IEEE TRANSACTIONS ON COMPONENTS AND PACKAGING TECHNOLOGIES, VOL. 28, NO.4, DECEMBER 2005,-0001,():
Ag70/Ni30 contact alloy is prepared by the process ofmechanical alloying and subsequent hot pressing. Results detectedby X-ray diffraction and transmission electronic microscope indicatethat this alloy is a mixture of "huge" Ag-rich matrix andmicro-scaled or nanocrystalline Ni-rich particles. The fine particlesstrengthen alloy mechanically and their uniform dispersion alsoimprove arc erosion morphology to a large extend, compared withsituation of traditional materials prepared through power metallurgytechnique.
