Pulsed plasma arc deposition (PPAD) was successfully used to fabricate the Ni-based superalloy Inconel 625 samples. The effects of three heat treatment technologies on microstructure and mechanical properties as-deposited material were investigated. It found that structure exhibited homogenous cellular dendrite structure, which grew epitaxially along direction. Moreover, some intermetallic phases including Laves phase MC carbides precipitated in interdendritic region as a result Nb...
The IN738LC Ni-based superalloy strengthened by the coherent γ'-Ni3(Al,Ti) intermetallic compound is one of most employed blade materials in gas turbine engines and thin wall components without macro-cracks were fabricated pulsed plasma arc additive manufacturing (PPAAM), which more competitive when considering convenience cost comparison with other high-energy beam technologies. as-fabricated sample exhibited epitaxial growth columnar dendrites along building direction discrepant secondary...
SiCN thin film is one of the most attractive silicon-based materials due to its excellent electrical, mechanical and optical properties. In this study, films have been prepared by radio frequency reactive magnetron sputtering method under different power, pressure, substrate temperature. The microstructure, morphology, field emission properties were performed. results indicated that high-quality successfully it proved these can be tailored preparation conditions. A main near ultraviolet...
12CrNi2 high strength steel thin wall with few defects was fabricated by laser additive manufacturing technology. The microstructure of as-built sample studied using optical microscopy (OM), scanning electron (SEM) and energy dispersive spectroscopy (EDS). Additionally, the mechanical property also investigated microhardness tests. It found that mainly consists columnar dendrites aligned in building direction because fast directional cooling during LAM. Cellular grains, equiaxial are...
