National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

The Cladding and Welding of Stainless Steel to Molybdenum and Niobium.

PB166052

Publication Date	1959
Personal Author	Fugardi, J.; Zambrow, J. L.
Page Count	43
Abstract	Methods were investigated for the fabrication of composite sheets consisting of 310 stainless steel bonded to one side of either molybdenum or niobium sheet. A barrier material between the two sheets was used to minimize diffusion. The best barrier material found, on the basis of tensile strength, thermal shock resistance, minimum diffusion during long time high temperature tests and minimum formation of intermetallic compounds at the bonding surfaces, was nickel for the molybdenum to type 310 stainless steel composite and iron for the niobium to type 310 stainless steel composite. Butt welds were made on composite sheets of stainless-molybdenum and stainless-niobium. The difference in the thermal coefficient of expansion between the stainless and the refractory metals used caused stresses and distortion in the weldments. (Author)
