## Description

- description: To clarify the effect of solution heat-treatment on the oxidation resistance
    of Ni-base single crystal superalloy TMS-238, evaluation of dendrite/inter-dendrite
    segregation of alloying elements in as-cast and heat-treated samples, and its
    effect on cyclic oxidation resistance were investigated. Cyclic oxidation test
    results at 1100 °C for up to 150 cycles clearly showed that the as-cast samples
    with element segregations had lower oxidation resistance compared to heat-treated
    samples with homogeneous structure. Further, for the as-cast sample, rapid growth
    and spallation of oxide consisting of NiO, Cr2O3, and Al2O3 were observed around
    the dendrite core even for 10 cycles oxidation. Analysis of sub-surface on sample
    isothermally oxidized at 1100 °C for 10 min showed that rapid oxide growth is
    due to the formation of discontinuous Al2O3 layer at dendrite core with lower
    Al concentration. Furthermore, in this study, the threshold value of Al concentration
    and Gibbs energy for the formation of continuous Al2O3 layer were estimated and
    determined to be around 5.2 wt.% and -"556.6 ± 0.5"  kJ/mol, respectively. This
    indicated that the solution heat-treatment for TMS-238 should be conducted above
    1305°C for exhibiting oxidation resistance at 1100 °C, to meet the threshold value
    within the whole region between dendrite to inter-dendrite.
