Title:
押し出し異形材を製造するための粉末冶金方法
Document Type and Number:
Japanese Patent JP2010533238
Kind Code:
A
Abstract:
In a process to heat metal powder and extrude this as a profile, the powder is heated to a temperature below that of the melting point. The powder is extruded under pressure through a matrix aperture and converted to a profile. The metal or metal alloy powder is a reactive material whose outer surface spontaneously forms a natural, protective oxide layer. The powder further incorporates fibrous particles that absorb microwaves. The powder is heated to extrusion temperature by exposure to microwave energy.
