Process of Producing Parts of Complex Shape by Molding and Sintering Iron and Iron Oxide Powders with a Binder

The paper describes a new process of producing structural steel parts by molding mixtures of iron and iron oxide powders with a binder, reducing the oxides in vacuum with nanosized products from pyrolysis of the binder, and sintering. It is shown that this process has advantages over conventional pr...

Summary:The paper describes a new process of producing structural steel parts by molding mixtures of iron and iron oxide powders with a binder, reducing the oxides in vacuum with nanosized products from pyrolysis of the binder, and sintering. It is shown that this process has advantages over conventional pressing and sintering as well as the MIM process: it allows parts of complex shape to be produced and the cost of products to be decreased.
