This powder could be cold- sprayed, all the more easily because of a fine grain size.
MA process was first developed more than 30 years ago for the production of composite metallic powders [1, 2] and was used to synthesize a number of commercially-important alloys and composites.

It was noted that after a certain number of procedures in which gypsum was subjected to recycling, there was a loss of workability; however, it did not present relevant changes in mechanical properties.

This allows the program to be able to use the coarse-grained data object transmission to improve the efficiency of remote transmission
Add XML configuration file in the control layer The Cairngorm framework does not provide any configuration files, resulting in the mapping between the view layer of the spread of events and the corresponding business process class changes must modify a large number of pages or code.
E4X as a good solution for XML operations, has been a number of emerging programming language to accept and realize, the most typical is ActionScript 3.0 for Flex / Flash programming that it is similar to JavaScript.

When the vibration level due to flaking reached the preset condition of the sensor, the operation was terminated and the number of rotation was recorded as the rolling contact fatigue life of the specimen.
Fig. 3 are the curves of Hertzian stress vs. number of cycles for SAE52100 and AISI4140 specimens, respectively, obtained from the tests under grinding and UNSM.
This causes stress distribution until spall nucleation, and fatigue life improvement can be explained by the combined effect of grain refinement, compressive residual stress, and surface topology.

In order to define the exact energy position of the shallow dislocation-related states with respect to the conduction band we utilized the fact that under application of forward bias voltages Uf our structures behave similar to the grain boundaries or MIS structures where the filling grade of the interface traps is controlled by the potential at the interface.
b) The reduction of activation energy for electron thermoemission from the local electronic states in the core of 60o dislocation as a function of number of electrons in the dislocation core and of applied forward bias to the Schottky diode with the bonded interface at the depth of 160 nm: dotted line – was calculated according to the model of negatively charged dislocation line with an attractive dislocation deformation potential; solid line – the same but with adding of outer electric field of the diode; black dots – the data of energy resolved DLTS.
The own electric field due the non-screened Coulomb potential of dislocation line (Fig. 3a, curve 1) can be written as (1) where q is elemental charge, is dielectric constant, Nl is the number of electrons per length unit of dislocation, r is the distance from dislocation, rcore is the radius of charged core, Ns is the averaged density of the electrons per area unit, D is the interdislocation distance in the bonded interface.

Shot blasting improves the surface energy and nucleation density, which leads to the crystal grain fine of the corrosion products and the oxide film, obtains a dense barrier layer, inhibits the spot corrosion, and improves the corrosion resistance of Al-Cu alloy in test soil.

Introduction In the Czech Republic, the number of heating plants fueled by various types of straw (rape, wheat, etc.), wooden chips and pellets has been increased over the last few years.
The principle of determination of shape index is to measure the thickness E and length L of each grain in a sample of several hundred stones and then to calculate the ratio L/E between the smallest and the longest size of each particle.

Coatings produced by FS are also known to be free of pores and solidification cracks and present a fine grained structure caused by dynamic recrystallization during the process [2, 8].

As expected, such kind of equations requires complex and expensive laboratory trials to obtain the flow stress as a function of grain dimension, dislocation density, etc.
Equivalent stresses (s) and deformations (e) were derived from t and γ as: where M is the torque in Nm, N the number of revolutions.
· In that way each complex equation can be put in the linear form: (7) The same consideration can be made for equations characterised by a more elevated number of variables.

Introduction The process of production of high-energy permanent magnets (HEPM) having rare-earth metals, using the method of powder metallurgy, includes the stage of production of powders of appropriate alloys having desired size of grains and physical-mechanical parameters.
On a number of occasions the reaction proceeds rather actively even at a room temperature.
In a number of cases, metallographic samples of the alloy were used as a preform to carry out the metallurgical study of modification of the sample surface during hydrogenation.
