Abstract:

The formation of a zirconium carbide with a composition close to stoichiometric and, consequently, a maximal heat resistance for a soldered joint is observed at a soldering temperature of 2500C and a holding time of no less than 4 min. Similar results are obtained when the soldering temperature is reduced to 2000C while the holding time at this temperature is no less than 2 h. The optimal soldering regime for molybdenum is a soldering temperature of more than 2200C and a holding time of no less than 3 min. For soldering under optimal conditions with specimens heated to 2000C the strength of the weld is, as a rule, as great as that of the base material. Author
