Abstract:
1. A method of producing a metal matrix composite having at least one desired and controlled application specific property, the method comprising the steps of: selecting at least one micro-engineered particulate; mixing the micro-engineered particulate with a powder substrate; pre-consolidating the mixed powder to form an article or near net shape article; consolidating the article or near net shape article to produce the metal matrix composite exhibiting the at least one desired and controlled application specific property; wherein the consolidating step comprises dual mode Dynamic Forging, said dual mode Dynamic Forging comprising the steps of: controlling a rate of applied pressure during the first and second modes by means selected from the group consisting of: controlling a pressurization rate in a range of 2″/min to 120″/min; and, controlling a decompression rate so as not to exceed 120″/min.
