Failure of a Dissimilar Metal Braze in an Expansion Joint ...

Similarly, the AWS Brazing Handbook in the chapter on Brazing Filler Metals indi es that copper–phosphorus filler metals “should not be used on ferrous or nickel-based alloys, or on copper-nickels with more than 10% nickel, to avoid formation of brittle, intermetallic phosphide compounds” . Unfortunately, that is the entirety of the ...

Reactor pressure vessel embrittlement

This degradation was attributed to both high copper and phosphorus concentration and high neutron fluence. Consequently, as the first WWER-440/213 units were fabri ed using basically the same technology, at least the reactor vessel material properties are very similar to WWER-440/230 units despite the design improvements adopted.

Properties and appli ions of electroless nickel

phosphorus content of electroless nickel has a very sig-nificant effect on its melting point, as shown in Figure 2. The final melting point curve declines almost linearly from 1455 C to 880 C for an alloy containing 11% phosphorus. This is the lowest melting point eutectic for the nickel/ phosphorus
