摘要：
Brazing Mo/Mo and Mo/porous W using 60Mo-40Ru in weight percent braze alloy are evaluated in the experiment. Sound Mo/60Mo-40Ru/Mo joint is obtained from brazing at 1970 and 2000 degrees C for 600 s, respectively. The brazed joints are comprised of sigma and Mo-rich phases. For Mo/60Mo-40Ru/porous W joint, sound bonding is achieved only from brazing at 2000 degrees C for 600 s, and similar microstructure of the joint is obtained. The 60Mo-40Ru braze alloy shows potential in bonding refractory metal(s) for high-temperature applications.
