Interpretation of Nanocrystalline Materials
A plate of material that resembles a steel coil is gently pulled apart. The material is as soft as paper, but thinner than paper. The nanocrystalline ultra-thin ribbon with a thickness of only 14 microns was developed using new technologies. Many people have heard of nano and nanotechnology, but are very unfamiliar with "nanocrystals". What exactly are nanocrystals? Simply put, nanocrystals are a new ma

Characteristics of Nanocrystalline Materials
1. High magnetic induction: the saturation magnetic induction Bs=1.2T, which is twice that of permalloy and 2.5 times that of ferrite. The power density of the iron core is large, which can reach 15 kW to 20 kW/kg. 2. High permeability: The initial static permeability μ0 can be as high as 120,000 to 140,000, which is equivalent to permalloy. The magnetic permeability of the iron core of the power transformer is

Introduction to the characteristics of nanocrystalline cores
On the one hand, eddy currents can be isolated, and the data are suitable for higher frequencies; on the other hand, due to the gap effect between particles, the data have low permeability and constant permeability; due to the small particle size, there is basically no skinning phenomenon, and the permeability varies with frequency. The change is relatively stable; in addition, the powder core can be made into vari
