    • A brazing composition for the brazing of superalloys including a base material with at least one initial phase is provided. The initial phase has a solidus temperature that is below the solidus temperature of the base material and, above a certain temperature, forms with the base material and/or with at least one further initial phase at least one resultant phase, the solidus temperature of which is higher that the solidus temperature of the initial phases. Heat treatment takes place in two stages, wherein the temperature of the second heat treatment is preferably 800-1200° C. The brazing composition may likewise be of the type MCrAlX, and the power particles of the initial phase may be in the form of nanoparticles.
    • 提供了一种用于包含具有至少一个初始相的基材的超级合金钎焊的钎焊组合物。 初始相的固相线温度低于基体材料的固相线温度,高于一定温度,与基体材料形成,和/或与至少一个另外的初始相位形成至少一个所得相,其固相线温度为 高于初始相的固相线温度。 热处理分两个阶段进行,其中第二次热处理的温度优选为800-1200℃。钎焊组合物同样可以是MCrAlX型,并且初始相的功率粒子可以是纳米颗粒的形式 。
