Abstract (en)
[origin: US5308232A] The invention relates to powder metallurgy. The invention involves deforming combustion products by extrusion at an extrusion temperature chose in the range from 0.3T1 to T2, wherein T1 is the melting point of a hard phase of the combustion products and T2 is the melting point of a binder material in a container (5) made up of vertically extending segments (12) defining spaces (13) with one another and having a die (14) and a heat insulated sizing member (17) the temperature conditions of extrusion being controlled by a unit (21) having a temperature sensor (22) and a member (23) receiving information from the sensor (22) and sending a command for moving the punch (10).
