The structure and selected physical properties of the nanocrystalline Fe92.4Hf4.2B3.4 alloy

Crystallization Kinetics of Metallic Glasses

“…Most of the methods depend on the transformation rate equation given by Kolmogorov, Johnson, Mehl and Avrami Szewieczek & Lesz, 2004;Jones et al, 1986;Minic & Adnadevic, 2008), popularly known as KJMA equation, basically derived from experiments carried out under isothermal conditions. The KJMA rate equation is given by…”

The characterization of structure, thermal stability and magnetic properties of Fe–Co–B–Si–Nb bulk amorphous and nanocrystalline alloys

“…The applied magnetic field had the value of 0.5 A/m and frequency of about 1 kHz. The magnetic after effects ( / ) were determined by measuring the changes of magnetic permeability of the examined alloys as a function of time after demagnetization, where is the difference between magnetic permeability determined at t1 = 30 s and t2 = 1800 after demagnetization and at t1 [11][12][13][14][15][16]. High field magnetization curves were measured by a vibrating sample magnetometer (VSM) in a magnetic field up to 2 T. The magnetizing field was parallel to the sample length to minimize demagnetization effect.…”

Atomic layer deposition of TiO2blocking layers for dye-sensitized solar cells

“…Trends in the high-tech industry tend to miniaturization, the production of products with complex shapes, and multifunctional materials. To keep up with ever-increasing demands, scientists focus on developments and advancements in technology, processing and performance improvement (Bussmann-Holder et al , 2017; Jonda et al 2016; Kremzer et al , 2016; Luceno-Sanchez et al , 2019; Pakieła et al , 2016; Szewieczek and Lesz, 2004).…”
