Commercial Methods for Powder Production,is marked by the process used in its production. This variation is fortunate in some respects because it gives a wide range of properties from which to choose a powder. The same variation from process to process has an unfortunate aspect because it makes the development of standard grades of metal p

The Pressing and Sintering Properties of Iron Powders,one there is a choice of some twenty different iron powders for powder-metallurgical purposes, and it is known that a number of new production processes are under development which will eventually lead to the introduction of further types of powders on the market.

High Velocity Compaction of Iron Powder,tional pressing and sintering. The lower properties of the latter stem primarily from their lower density. Some metal components, such as bearings and filters, require low density (high porosity) to retain oil, but in most applications the highest practical density is desirable for strength, ductili

Study on Continuous Rolling Fabrication of Iron Strip from Metal Powders,patent for this method was announced about sixty years ago , However, for a long time it has been buried under the conventional melting method. Since G. Naezer and F. Zirm published a paper on powder rolling of RZ iron powder, many experiments were carried out with various kinds of powders, such

Some Factors Influencing the Properties of Sintered Iron,hich influence the properties of sintered structural materials is still quite insufficient. Some such variables are, for example, the causes of differences in sintering activity and dimensional behavior between the commercial types of iron powder and the role of phase transformations and grain growt

Study of the Mechanical Properties of Porous Iron in Tension and Torsion,ength of such elements, it is necessary to have information on the ability of materials being employed to resist fracture in the presence of various combinations of the principal stresses. Porous materials prepared by powder metallurgy methods are no exception in this respect. The range of parts mad
