... was not of the distinctive copper color but was of a color resembling Monel, which is composed of copper and nickel. In the copper brazing of such base materials as nickel, Monel, or the copper-nickels, the solidus of the molten braze filler metal is increased, and the flow through the joint can be terminated. The remelt...

Conclusions The clapper failed by fatigue and brittle fracture because it was welded with an incorrect filler metal. Fatigue cracking was initiated at voids...

Face-centered-cubic (fcc) metals (for example, copper, aluminum, nickel, and austenitic steels) exhibit the greatest ductility during rapid fracture and, in benign environments, do not normally fracture via cleavage. However, brittle cracking of fcc metals can occur under conditions...
