Most metals are melted and cast with the furnace evacuated to the ultimate vacuum of the system at the beginning of the heat and with the vacuum valve of the furnace open throughout the run. The thermocouple gage, located in the vacuum line between the furnace and the main furnace valve, normally indicates an absolute pressure of 150 to 500
A major final step in powder metallurgy is sintering, a high temperature process that develops the final properties of the metal part. The compacted raw materials, called green parts, are heated in a furnace at temperatures below their melting point to bond the particles together without changing part's shape.
Nov 17, 2015 · Hydrogen Furnace Sintering is used widely as part of many powder metallurgy (PM) processes to create parts of extremely accurate size and uniformity. Stainless steel is common, but a other high-performance alloys, such as tungsten carbide and other alloys, also require high-temperature sintering in hydrogen.
Dec 01, 2005 · The process, derived from plastic injection molding, comprises four main steps of mixing of metal powder with a polymer binder, injection molding the mixture, binder removal (via heat treatment or chemical processes) and sintering or densification.
