The effect of thermal treatment on the microstructure of plasma sprayed coatings
 Matyáš, V. ; Buršík, Jiří
Several types of plasma sprayed protective coatings on Ni-based substrates were studied in the as-deposited state and after long term annealing at 1173 and 1273 K by means of analytical electron microscopy. The microstructure changes were detected and quantified.

Plasma sprayed protective coatings studied by analytical electron microscopy
 Matyáš, V. ; Buršík, Jiří
The formation of Al-rich phase dominates the microstructural changes at the interface of plasma sprayed protective coatings on Ni-based substrates during long term annealing at 1173 and 1273 K. Other changes in coating microstructure were detected and quantified by means of analytical electron microscopy.

Study of phase equilibria in Al-Cr-Ni-W and Al-Cr-Ni-Co alloys
 Picha, R. ; Buršík, Jiří ; Brož, P.
The quaternary systems Ni-Al-Cr-W and Ni-Al-Cr-Co were studied after long term annealing at 1173 K by means of analytical electron microscopy. The experimentally obtained quantitative parameters were used for thermodynamic modelling of phase equilibria using software Thermocalc.

Study and modelling of the gamma and gamma prime phase equilibrium in Ni-Al-Cr-Co system
 Brož, P. ; Buršík, Jiří ; Picha, R.
Several alloys of Ni-Al-Cr-Co system with constant Ni content of 70 at. % were studied after long term annealing at 1173 and 1273 K by means of analytical electron microscopy. The quantitative structural parameters showed good agreement with calculated data obtained by means of the software Thermocalc. Optimization of some thermodynamic parameters was performed.

TEM study of the P phase in model Ni-based alloys
 Buršík, Jiří
A microstructure of Ni-Al-Cr-Mo alloys was studied by means of analytical and high resolution TEM. The changes in grain boundary regions during annealing at 873 K include the growth of ordered domains and the precipitation of topologically close packed P phase, which typically exists in a narrow compositional range in Ni-Cr-Mo system.

Microstructural study of plasma sprayed coatings on Ni-Cr-Al alloys
 Svoboda, Milan ; Buršík, Jiří
The microstructure of CoCrAlY, NiCrAlY and CoCrNiWFe plasma sprayed coatings was studied by analytical TEM in the initial state and after thermal treatment. Annealing at 1173 K resulted in precipitation of fine Al-rich particles and formation of Al-depleted zone near the interface.
