Description
The authors study a nickel-based alloy with a high boron content, made for a repair method that rebuilds worn turbine blades. Boron is usually added in tiny amounts to strengthen grain boundaries in such alloys. What large amounts do is rarely studied. Using electron and X-ray tools, the team tracks which phases form in the alloy and how they change during heat treatment.
Boron-rich particles, rich in chromium, tungsten, and molybdenum, make up about 8 percent of the material. They shrink as heating time and heat rise, and they nearly vanish after two hours at 1160 degrees. Their melting creates boron-rich zones with a low melting point, which can bond the repair piece to a blade below the blade's own melting point. Hardness inside the grains first falls, then rises with hotter treatment, and the team tests the strength of the joined material.
