摘要：

The effect of addition of 0.2 wt.% B on the tensile and creep properties of Timetal 834 alloy was studied in the thermomechanically processed condition after subjecting it to different heat treatments. The 0.2% YS and UTS of the boron modified alloy was found to be higher than that of the base alloy irrespective of the heat treatment employed. The creep strain for 100 h as well as the steady state creep rate at a temperature of 600 degrees C and initial stress of 150 MPa stress was also significantly lower for the B modified alloy. The results were explained on the basis of load sharing by the TiB whiskers. (C) 2011 Elsevier B.V. All rights reserved.
