This paper presents a study for making micro 316-L stainless steel components by soft lithography in combination with powder metallurgical processes. 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. Powder Metallurgy Stainless Steels—Processing, Microstructures, and Properties Erhard Klar and Prasan K. Over the years, Crucible's product patents have included: Tool Steels, Bearing Steels, Stainless Steels, Valve Steels, Nickel Base Alloys, Cobalt Base Alloys, Tungsten Base Alloys, Titanium Base Alloys, Mold Steels, Composites, and Powder metallurgical processing confers unique features upon a material, including an absence of particle outlining, an extremely fine grain structure, the absence of macrosegregation, and improved forgeability and machinability. Erhard Klar, Erhard Klar, Prasan K. 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. This was not true for the HPDDL . But titanium, chromium, nickel, and stainless steel metal powders are also used. 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). In the majority of process because it is convenient, economical and flexible technique and perhaps the largest volume of metallurgy powders is made by the process of oxide reduction. Most important characteristics of metal powders are powder particle size, size distribution, particle shape, purity, chemical composition, flow characteristics and particle microstructure. 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. 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. Powder Metallurgy Stainless Steels: Processing, Microstructures, and Properties. 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.
