    Abstract

    Many variables are involved in the production of pressed and sintered compacts. These are reflected in the properties of the final product. This is true not only over the range of the various metals which can be handled in powder form, but also for any individual sample of a metal powder. The pressure used in forming the compact may often be the predominant factor in determining the final properties of the sintered material. On the other hand, the pressure range within which we can operate is determined by the physical properties of the metal particles, and more especially by their ductility. The actual pressure employed within the usable pressure range for a given powder will be determined by the physical properties desired. In some cases a porous product is desired; in others, one having a density as near to the theoretical as possible. This paper includes observations made on the effect of the pressure used in forming compacts from iron and steel powders through a pressure range up to 160 tons per sq. in.
