the necessary mechanical properties. Hot forging produces an oxide scale that has to be removed mechanically or chemically, if the stainless steel is to be corrosion resistant (i.e., be passivated). The water in the quench-tempering bath was found to be high in chloride, which was retained within the oxidized More

... for producing wire using the powder-in-tube method. Powder-in-Tube Processing The powder-in-tube approach is the most common method used to date for producing an oxide-base wire or tape. The oxide precursor powder is packed into a hollow metallic tube. Usually silver or gold are preferred due...
