摘要: Abstract Pure palladium and silicon powders have been mechanically alloyed by ball milling technique. Two compositions were investigated, namely Pd 75 Si 25 , corresponding to the stable intermetallic compound 3 Si, 80 20 . It has found that amorphization process, monitored X-ray diffraction, proceeds via formation of for both examined. Complete is never reached in these samples but a higher amorphous fraction always present sample. The experimental results interpreted light schematic free-energy diagram binary system.
