摘要

The influence of the BT3- 1 alloy structure on creep at temperatures 400-5000C has been studied. An abrupt change of the creep mechanism has been shown to take place in the vicinity of the upper operating temperature of this alloy (450+-50 deg C). It has been found that at temperatures below 450 deg C the structure produced by RHT has the highest resistance to creep. At 500 deg C the lamellar structure has the lowest steady state creep rate.
