Summary: An alloy design computer program for Ni-base superalloys. The microstructural parameters and high temperature properties of Ni-base single crystal superalloys with any composition are predicted by this program. (e.g, Harada H, et al: Proc. of 5th Int. conf. on Creep and Fracture of Engineering Materials and Structures, Swansea, Wales U.K., The Institute of Materials; 1993, p255.)

Summary: An alloy TMS-75 with a multi chemical composition, having 3 wt% Cr, 5 wt% Re, etc. has a good balance of creep strength over intermediate and high temperatures. Typical creep rupture lives at 900 deg.C - 392MPa and 1100 deg.C - 137MPa being 961h and 227h, respectively. (e.g, Kobayashi T, et al: 4th Charles Parsons Turbine Conference. Newcastle upon Tyne (U.K.) 1997. p.766.)

Summary: An alloy TMS-82+ with a moderate 2.4 wt% Re addition, has a higher creep rupture strength than the second generation single crystal superalloys such as CMSX-4 and Rene N5, and even the third generation single crystal superalloys. Typical creep rupture lives at 900 deg.C - 392MPa and 1100 deg.C - 137MPa being 584h and 375h, respectively. (e.g, Hino T, et al: Superalloy 2000, Seven Springs (PA): The Metallurgical Society; 2000. p.729.)

Summary: The displacement of specimen during the creep test is detected by the image processing using two marker images of specimen through high resolution CCD camera. This Extensometer is a non-contact type, and it can eliminate the factor of measuring error due to the deformation of extensometer itself at high temperatures over 900 deg.C.
