Production and Structural Characterization of NiB Nanoalloy Synthesized by Ball Milling

2016-10-01
Ni-B nanocrystalline alloy/intermetallic phase powders have been synthesized via mechanical alloying by using high-energy ball milling. The effects of milling time on phase formation, microstructure and magnetic behaviors have been investigated. Milling operation has been carried out with two different compositions of Ni-B alloys as Ni80B20 and Ni60B40 up to 80 hours of milling time. Initial sub-micron sized particles have been reduced down to a size ranged in between 20 nm to 110 nm at the end of ball milling procedure. Structural analyses showed that in the Ni-B nanoalloys a Ni3B intermetallic phase were formed for both compositions of alloys under investigation. Additionally, Ni2B intermetallic phase formation have been detected in Ni80B20 nanoalloy. Magnetic measurements indicated a general decrease in saturation magnetization and increase in coercivity and also in hysteresis area with increasing milling time for both samples.

Akın, Özlem; Aras, Leyla; Department of Polymer Science and Technology (2004)
In this study, waterborne silicone-acrylic resin was produced by incorporating silane coupling agent onto the acrylic main chain by emulsion polymerization. After applying different emulsion polymerization processes, batch polymerization was selected to obtain the resultant resin. Thus finding the optimum conditions by investigating the parameters of monomer ratios, initiators, concentrations of initiators, temperature and time, the novel resin was synthesized. Water-dispersed silicone-acrylic resin was pro...

The effects of organoclay type, compatibilizer type, and mixing order of components on the morphology, thermal, mechanical and flow properties of ternary nanocomposites were investigated. Terpolymer of ethylene/butyl acrylate/maleic anhydride, ethylene/methyl acrylate/glycidyl methacrylate, and copolymer of ethylene/glycidyl methacrylate elastomers were used as compatibilizer, whereas ...
Preparation and characterization of polymer composites containing boron compounds
Topçuoğlu, Elif; Bayram, Göknur; Sezgi, Naime Aslı; Department of Chemical Engineering (2016)
Epoxy (EP) is a thermosetting polymer which has high dimensional stability. However, the brittleness, low resistance to impact failure and flammability are some limitations of the epoxy polymer. These properties limit the usage of epoxy in the applications where high mechanical strength and flame retardancy properties are needed. The purposes of this study are to improve both mechanical and flame retardancy properties of epoxy by the addition of boron containing compounds (BCC) mainly boron carbide (B4C), a...

Kaplan, Melis; PARK, JONGEE; Kim, Soo Young; Öztürk, Abdullah (Elsevier BV, 2018-02-01)
Dense zirconia stabilized with 3 mol% yttria ceramics were produced in disc shape by first cold isostatically pressing at 100 MPa and then sintering at 1450 degrees C at ambient laboratory conditions. Coloring was accomplished by immersion the discs in NiCl2, MoCl3, and NiCl2 + MoCl3 solutions for 5, 30, and 60 s. Different concentrations (0.1, 0.25, and 0.5 wt%) were applied to get the color of natural tooth. The density, color, microhardness, fracture toughness, compressive strength, and wear rate of the ...
