Powder Metallurgy Stainless Steels: Processing, Microstructures, and Properties. Aero-engine and land-based gas turbine applications for Powder Metallurgy products require extremely good properties and the PM-based process routes in this sector generally incorporate Hot Isostatic Pressing (HIP). Other Processing 1) Foundry practices 2) Powder metallurgy practices 3) Tube making. Corrosion testing was performed on the stainless steel samples by immersing the clad and substrate in nitric acid for a period of twenty-four hours to determine the effect of the acid on the substrate and clad. Powder-metallurgy parts, commonly referred to as P/M parts, are produced by the powder-metallurgy process, which involves blending of powders, pressing the mixture in a die, and then sintering or heating the compact in a controlled atmosphere to bond the contacting. Stainless steel and aluminum powders are still the main materials for powder metallurgy but titanium and titanium alloys offer unparalleled advantages. This was not true for the HPDDL . This paper presents a study for making micro 316-L stainless steel components by soft lithography in combination with powder metallurgical processes.

Also, prealloys such as low-alloy steels, bronze, brass, nickel-silver, and stainless steel are produced in which each particle is itself an alloy, thus ensuring a homogeneous metallurgical structure in the part. Erhard Klar, Erhard Klar, Prasan K. Laser alloying experiments were not conducted in this study;however, throughout the experimentation there was an expectation that at a low process speed some alloying of the powder and substrate would occur. B) tensile properties c) toughness d) high temperature behavior e) formability and machinability 3) Corrosion and Oxidation Resistance a) influence of alloy b) influence of microstructure c) intergranular d) pitting and crevice corrosion e) general 3) influence of metallurgical properties 4) influence of inclusions 5) influence of tool material.

For nickel-based superalloy turbine discs, HIP powder products in a range of austenitic and duplex stainless steels are also being increasingly used in off-shore applications, including manifolds and valves.
