Abstract
A process of brazing cracks and gaps in a single crystal article which takes places isothermally under the following conditions: the temperature of the isothermal solidification is between TLiqidus, Braze+5*(wt-%BBraze) and (Tsolidus, base material−70*(wt-%BBraze)), while (wt-%B*wt-%Cr) is between 15 and 40 and (Tsolv.&ggr;′, base material−TLiqidus, Braze) is above 140° C. This results in an homogeneous &ggr;/&ggr;′-microstructure of the isothermal solidified, brazed joint with mechanical properties similar to those of the base material.
