Abstract
The present invention provides for iron-based metallurgical powder compositions that contain nanoparticle metal or metal oxide flow agents useful for enhancing the flow characteristics of the compositions, particularly at elevated processing temperatures. The iron-based powder compositions can be advantageously blended with a flow agent such as a silicon oxide or iron oxide, or a combination of both, to provide a powder composition having improved flow properties and ejection release characteristics.
