Phase transformation of cobalt induced by ball milling

Under different mill intensity or different milling time the phase transformations follow the routes of hcp fcc→hcp hcp fcc→hcp→fcc hcp and hcp fcc→hcp→fcc hcp→fcc respectively. Our results indicate that the phase formation of cobalt induced by ball milling

Mechanical path to a photogenerated structure ball

Ball milling of blue-emitting crystal 1B of gold(I) isocyanide complex 1 induces a phase transition to yellow-emitting powder 1Y G which has the same solid structure as the previously reported 1Y obtained upon photoirradiation of 1B.This is the first example

RAPID COMMUNICATION Field-ball milling induced anisotropy

Based on in situ observations of the field-ball milling in a transparent container the mechanism of field-induced anisotropy in the nanostructured hard magnetic particles is discussed. Nanocomposite hard magnetic materials have drawn considerable attention for

Decomposition and Crystallization Induced by High-Energy

Phase transformation induced by ball-milling was studied in this work. It was found that amorphous Fe90Zr10 ribbons undergo crystallization into BCC α-Fe(Zr) under milling in an AGO-2 mill. The decomposition degree of the amorphous phase increased with increasing milling time and intensity. Analyses of samples milled at different speeds suggested that the observed crystallization is a

Transformations in oxides induced by high-energy ball-milling

This paper by no means exhaustive focuses on high-energy ball-milling of oxides on their mechanically induced changes and on the consequences of such changes on their physical and chemical properties.High-energy ball-milling offers a fortunate combination of technical simplicity and of complexity both of physical mechanisms which act during milling and of mechanosynthesized materials.

Reaction between LiBH 4 and MgH 2 induced by high-energy

Previous studies of ab initio density functional theory (DFT) calculations have predicted that reactions between LiBH 4 and MgH 2 can take place at temperature near 200 °C. However such predictions have been shown to be inconsistent with many experiments. Herein we have designed a novel process termed as ball milling with aerosol spraying (BMAS) to prove for the first time that the

Nov 15 2006 · The ball milling-induced reduction of MoS2 by Al has been investigated. Although this is a highly exothermic reaction that based on its thermodynamic properties should progress as a self-sustaining process ignition could not be achieved by ball milling. In order to identify the reason XRD particle size distribution SEM and DTA measurements were carried out on a series of samples milled

This paper investigates the effect of milling atmospheres on mechanical crystallization of an amorphous Fe 78 Si 9 B 13 alloy during ball milling. Under an air atmosphere the amorphous alloy completely transforms into a single α-Fe(Si) phase after milling of 30 h.

Ball Milling-Induced Plate-like Sub-microstructured Iron

The remediation of soil contaminated by 1 1 1-trichloro-2 2-bis(4-chlorophenyl) ethane (DDT) has been a challenge. In this paper the degradation performances of the ball milling-induced plate-like sub-microstructured zero valent iron (SMZVI) to DDT in a real soil environment is studied. It has been found that such SMZVI exhibits much higher degradation performances to DDT in soil than
