The IN738LC Ni-based superalloy strengthened by the coherent γ′-Ni3(Al,Ti) intermetallic compound is one of the most employed blade materials in gas turbine engines and IN738LC thin wall components without macro-cracks were fabricated by pulsed plasma arc additive manufacturing (PPAAM), which is more competitive when considering convenience and cost in comparison with other high-energy beam additive manufacturing technologies. The as-fabricated sample exhibited epitaxial growth columnar dendrites along the building direction with discrepant secondary arm spacing due to heat accumulation. A lot of fine γ′ particles with an average size of 81 nm and MC carbides were observed in the interdendritic region. Elemental segregation and γ–γ′ eutectic reaction were analyzed in detail and some MC carbides were confirmed in the reaction L + MC→γ + γ′. After standard heat treatment, bimodal distribution of γ′ phases, including coarse γ′ particles (385 nm, 42 vol.%) and fine γ′ particles (42 nm, 25 vol.%), was observed. The mechanism of microstructural evolution, phase formation, as well as cracking mechanisms were discussed. Microhardness and tensile tests were carried out to investigate the mechanical performance. The results show that both the as-fabricated and heat-treated samples exhibited a higher tensile strength but a slightly lower ductility compared with cast parts.

We developed a synthesis method of nanomaterials by the impulse plasma in liquid. The method is based on the low voltage pulsed plasma. The apparatus is very simple and does not require vacuum system, high-energy, cooling system, but can evaporate even refractory metals. Preparation experiments of nanomaterials by using Impulse Plasma in Liquid method were performed. We succeeded in synthesis of nanocrystals of some metals, TiO2, and fullerene C60. The synthesized TiO2 powder consists of fine-dispersed particles of rutile and anatase phases with 5-15 nm grain size. Pure fullerene C60 was prepared by dispersion of graphite electrodes by Impulse Plasma in toluene. It was suggested that the present method can be effectively used for nanomaterials preparation.
