The influence of short-time milling on the atomic structure of amorphous Co(70.3)Fe(4.7)B(25) has been investigated by differential scanning calorimetry (DSC), x-ray powder diffraction (XRD), vibrating sample magnetometer (VSM) and x-ray absorption fine-structure (XAFS) techniques. Our results prove that the milling process crystallizes the initially amorphous sample and that the degree of inhe...

We have measured X-ray absorption near edge structure (XANFS) of mechanically alloyed YzFe and YFez system as a fundion of milling time. An amorphous phase is obtained by mechanical alloying for 100 hours in the YzFe system and for 500 hours in the YFez system. In both systems the intensity of Fe Is-4pn transition grows up significantly with increasing the milling time and approaches to that of...

This paper proposes a method to vibration analysis in order to on-line monitoring of milling process quality. Adapting envelope analysis to characterize the milling tool materials is an important contribution to the qualitative and quantitative characterization of milling capacity and a step by modeling the three-dimensional cutting process. An experimental protocol was designed and developed f...

The adaptronic spindle for milling machines can be positioned by piezoelectric actuators in three axial directions. This enables an automatic online-compensation of tool deflections in the milling process. The tool deflection is calculated by the process forces and the tool stiffness previously measured. A new spindle position is calculated to counteract the tool deflection. This procedure can ...

The nanomechanical properties of carbon nanotubes particulate-reinforced aluminum matrix nanocomposites (Al-CNTs) have been characterized using nanoindentation. Bulk nanocomposite specimens containing 2 wt % multiwalled CNTs (MWCNTs) were synthesized by a combination of ball milling and powder metallurgy route. It has been tried to understand the correlation between microstructural evolution pa...

Laser milling provides a new method of producing components for the micro tool manufacturing industry. This paper considers the technical capabilities of laser milling when applied to the machining of components for micro tooling. Characteristics important for laser milling as a micro tooling manufacturing process are reviewed. These characteristics are surface finish, aspect ratio, dimensional...

This paper proposes a method to vibration analysis in order to on-line monitoring of milling process quality. Adapting envelope analysis to characterize the milling tool materials is an important contribution to the qualitative and quantitative characterization of milling capacity and a step by modeling the threedimensional cutting process. An experimental protocol was designed and developed fo...

Cereal Chem. 86(4):470–476 The degree of similarity between rice milled in a McGill #2 laboratory mill and commercial milling processes was evaluated using eight physical, physicochemical, and end-use properties. There was no statistical difference between the two milling systems with respect to color parameters L* and a*, final viscosity, texture, and end-use cooking properties (α = 0.05). Ove...

The mechanical alloying process was used to synthesize the Ni50Al50−xMox nanocrystalline intermetallic compound using pure Ni and Al elemental powder. This process was carried out in the presence of various Mo contents as a micro-alloying element for various milling times. Structural changes of powder particles during mechanical alloying were studied by X-ray diffractometry (XRD) and scanning e...
