Sep 13, 2019· Powder Metallurgy (PM) superalloys are renowned for the uniformity of microstructure, macrosegregation-free, fine grain, high yield strength and superior fatigue properties . Among them, the third-generation PM superalloys have excellent resistance to corrosion, fatigue, creep and crack propagation, and excellent high-temperature strength [ 4 ].
The Poisson's ratio for the TGO is 0.22, bond coat is 0.3 and the TBC is 0.22 [115]. Nano-TBC is obtained by synthesizing nanostructured 7%YSZ powders to microagglomerates so as to make feedstock that is suitable for being fed and thermally sprayed using conventional powder feeders or through solution precursor technique [116].
The hafnium atom has a radius of 159 pm and a Van der Waals radius of 212 pm. Hafnium was predicted by Dmitri Mendeleev in 1869 but it was not until 1922 that it was first isolated Dirk Coster and George de Hevesy. In its elemental form, hafnium has a lustrous silvery-gray appearance. Hafnium does not exist as a free element in nature.
