Investigation of oxidation behavior and Thermal spray of mechanically milled CoNiCrAlY–YSZ powders

In this study, the effects of mechanical milling and YSZ reinforcing on oxidation behavior of CoNiCrAlY coatings were investigated. Various amounts of YSZ particles (0%, 5%, 10% and 15 wt.%) were mixed with commercial CoNiCrAlY powder and milled for 24 hrs. Then, the mechanically milled and commercial powders were deposited on Inconel 617 substrate using High Velocity Oxygen-Fuel (HVOF) process...

Spark Plasma Co-Sintering of Mechanically Milled Tool Steel and High Speed Steel Powders

Hot work tool steel (AISI H13) and high speed steel (AISI M3:2) powders were successfully co-sintered to produce hybrid tool steels that have properties and microstructures that can be modulated for specific applications. To promote co-sintering, which is made difficult by the various densification kinetics of the two steels, the particle sizes and structures were refined by mechanical milling ...

Effect of fuel content on structural and magnetic properties of solution combusted Mn0.8Zn0.2Fe2O4 powders

Single phase Mn0.8Zn0.2Fe2O4 powders were synthesized by solution combustion method. The solution combustion method relies on the exothermic self-sustained reactions in reactive solution containing of oxidizers and organic fuels. In this work, the effects of various amounts of glycine as fuel on the powder characteristics were investigated. The structure, cation distribution, microstructure, ma...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
