The factor that determines the flow characteristics of the segregation-free ion mixed powder which contains ethylene-bis-stearamide as a lubricant powder was investigated. Sample powders used were as follows: (A) iron powder (B) iron powder mixed with ethylene-bis-stearamide powder (C) iron powder mixed with graphite powder (D) iron powder bonded with graphite powder by the organic binder(binder treated iron powder) and (E) binder treated iron powder mixed with ethylene-bis-stearamide powder. Iron powder gave the best flow character and the binder treated powder with the free lubricant powder gave the worst flow character. The data above mentioned and the data related to the frictional properties of the sample powders indicated that the interaction between the binder on the iron powder and the lubricant powder or the interaction between the lubricant powders affected strongly on the flow characteristics of the segregation-free iron mixed powder containing ethylene-bis-stearamide as a lubricant.
