| Abstract | Quite recently, boron-free nickel base filler metals wi th small amounts of phosphorus (compared to standardized phosphorus-containing filler metals) were developed for use, especially in nuclear industries. These filler metals can be brazed at temperatures similar to those of low melting boroncontaining nickel-base filler metals. By varying brazing parameters such as process atmosphere, clearance, condition of brazing surface, or brazing time and temperature, the structure in the high temperature brazed joint wi l l be considerably influenced and, wi th that, its quality or strength properties. The study discussed in this paper demonstrates the influence of different brazing temperatures and brazing times wherein all other brazing parameters were constant. The investigations were made at base metal-filler metal combinations between three types of filler metals wi th one base metal. These filler and base metals are characterized in Tables 1 and 2. Table 2 shows the 0.2% yield strength R„, and the ultimate tensile strength Rra at time of supply and after heat treatment during the brazing cycle. The AWS single-lap shear test specimen was used for strength determinations.- |
