摘要： A process for making a metal tool having controlled porosity is disclosed. The process includes the step of preparing metal powder by gas atomization. The metal powder is filled into a metal container. The powder-filled container is placed in a metal vessel and surrounded with glass frit. The metal vessel is then heated to a temperature sufficient to melt the glass frit. The metal vessel is then compacted under sufficient pressure to partially consolidate the metal powder so as to retain porosity therein in an amount sufficient to permit air to vent through the metal tool.

摘要： A process for preparing a duplex ferromagnetic alloy article is disclosed. The process includes the step of providing an elongated intermediate form of a ferromagnetic alloy having a substantially fully martensitic structure. The martensitic intermediate form undergoes an aging heat treatment under conditions of temperature and time that are selected to cause controlled precipitation of austenite in the martensitic alloy. The aged article is then cold-worked to a final cross-sectional dimension, preferably in a single reduction step, to provide an anisotropic structure and a coercivity, H.sub.c, of at least 30 Oe.

摘要： A process for cold working an elongated form of a steel alloy includes the step of forming a matte texture on substantially all of the surface of the elongated form. The matte texture is characterized by a plurality of random, minute, shallow indentations, uniformly distributed on the elongated form's surface. The process provides an elongated form of steel alloy that has a significantly improved capability to carry lubricant into a cold working tool or die, thereby benefiting the cold workability of the elongated form. An apparatus for carrying out the process according to the invention, in line with one or more other processing operations is also disclosed.
