Das pulver wird in loser schüttung gesintert. Die klassen sint- af bis sint- c werden durch pulvermischen, pressen und. Sintering is a manufacturing process in which a fine powder that has been formed into a shape is subsequently fired at temperature below melting point. Dabei wird die formgebung von einer wärme- beständigen hohlform übernommen. Introduction powder metallurgy ( pm) as a generic term includes all techniques to produce solid- metal- based products from powders. Sintern zur herstellung der klasse sint- af nimmt dabei eine sonderstellung ein, weil das übliche pressen des pulvers zu einem grünling entfällt. Authors: show all 10 authors.

This article provides information on the mechanisms and theoretical analysis of sintering and focuses on the types, mechanisms, process and microstructural variables, computer simulation, stages, and fundamentals of densification and grain growth of solid- state sintering and liquid- phase sintering.
Rapid synthesis and sintering of metals from powders. This involves powder production ( for which numer- 13 abstract aln substrates of high quality can be sintered in dif- ferent furnace types with firing programs adapted to the specific product requirements. A finite element model has been used to study the sintering process of polytetrafluoroethylene ( ptfe) cylinders in order to predict residual thermal stresses; both solid ( rods) and hollow ( billets).
