Abstract

A test for determining the bonding shear strength of a clad metal and the fixture for performing the test are described. The test specimen, which is relatively easy to machine, has approximately nine shear steps ranging in depth from shallower than the cladding to deeper than the cladding. Thus, at least one of the shear lips gives the shear strength very near the interface between the cladding and the base metal. Test results on a variety of bimetals are presented. Results are compared with ASTM Specification for Corrosion-Resisting Chromium Steel Clad Plate, Sheet, and Strip (A 264) criteria. This work was conducted by the Bureau of Mines, U.S. Department of the Interior, as a part of its effort to develop vacuum rolled claddings to conserve strategic materials.
