• B-1 Rafting Test of Single Crystal Superalloy by High Thermal Stress Using the Burner Rig Test Equipment.

抄録

Single crystal superalloy, TMS-138, were tested by only thermal stress at about 1000 degree of maximum material temperature for 100 cycles and for 1000 cycles (3 minutes heating and 3 second cooling). The result show that raft stricture under the influence of only thermal stress occurred. This raft stricture developed parallel to the direction of thermal stress in compression because of a negative lattice misfit crystal designed TMS-138. Unfortunately, cracks and topologically closed packed (TCP) phases were also caused by 1000 cycle tests. Although TMS-138 was tending to reduce high-temperature oxidation resistant, the significant improvement of high-temperature oxidation resistant through the addition of Y or Cr was showed.
