Magnetoresistance in Nanostructured Co-Ag Prepared by Mechanical- Alloying
Abstroct Fine cobalt and silver powders have been ball-milled to yield a granular solid of composition CoSoAg7a in the form of coarse powder. The material is an intimate mixture of grains of fcc CO in a silver matrix. The cobalt is in the single-domain size range, and the samples exhibit coercivity (0.07 T at 296 K) and unusual thermomagnetic effects , including field-induced unidirectional ani...
متن کاملAging of a nanostructured Zn50Se50 alloy produced by mechanical alloying
The aging of a nanocrystalline equiatomic ZnSe alloy produced by mechanical alloying was investigated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC) techniques. The measured XRD patterns showed that Se atoms located at interfacial component migrated with aging giving raise to a crystalline selenium (c-Se) phase. DSC spectra of heat-treated samples at temperatures abov...
متن کاملStructure and properties of Al67Ti25Fe8 alloy obtained by mechanical alloying
Purpose: The goal of this work is to investigate structure and properties of powdersAl67Ti25Fe8 alloys obtained by mechanical alloying. Design/methodology/approach: The powders of the Al67Ti25Fe8 alloys were obtained by mechanical alloying method in a planetary Fritsh Pulverisette 5 mill. The changes of the constitution phases were tested by means of the X-ray diffractometer. The microscopic ob...
متن کاملSynthesis and thermal stability of nanocrystalline Mg-6Al-1Zn-1Si alloy prepared via mechanical alloying
Thermal stability and the kinetics of the grain growth of nano-crystalline Mg-6Al-1Zn-1Si alloy prepared via mechanical alloying (MA) were investigated. It started with elemental powders, using a variety of analytical techniques including differential scanning calorimetry (DSC), X-ray diffraction method (XRD), and scanning electron microscopy (SEM) coupled with energy dispersive spectrometry (E...
متن کاملStructural Transformation of Immiscible Metals Induced by Mechanical Alloying
X-ray absorption fine structure(XAFS) is used to investigate the local structural change of Fe60Cu40 and FegoCu20 with the ball milling time. The XAFS results verify that the solid solution of mechanically alloyed Fe-Cu samples are inhomogeneous. We propose that the bcc to fcc structural transformation of Fe small particles of Fe60Cuq0(160h) is induced by interfacial Cu atoms dissolving in smal...
