Material Selection and Tool Printing Modelling plasticine (sculptural plasticine) was chosen as a research material.
As a result of the experiment with reduction δ =2, typical metal defects (laying, pivot journal occurrence, strong ovality) were not found.
Deformation of metals has more distributed form in the contact zone with the tool, plasticine is characterized by higher localization in the journal area.

Magnesium gangue materials were floated at acidic pH using anion collector MG-2, while phosphate was depressed; In the second part, the Mg-removing concentrate was conducted a desliming process prior to cleaning flotation as amine collector GE-609 was sensitivity to slimes [10].
And then silicon gangue materials were floated at alkaline pH(pH=8.0) in the cleaning flotation by GE-609, and the pH value was regulated by Na2CO3.

Microstructural Development of Aluminum A201 Alloy Semi-Solid Processing Feedstock Produced by Different Routes Plato Kapranos Department of Materials Science & Engineering, the University of Sheffield, Sir Robert Hadfield Building, Mappin Street, Sheffield, S1 3JD, U.K p.kapranos@sheffield.ac.uk Keywords: A201 aluminum alloy, Magnetohydrodynamic Stirring (MHD), Strain Induced Melt Activated (SIMA), Semi-Solid Rheocasting (SSR), Cooling Slope (CS).
This microstructure gives the material its thixotropic properties; i.e. the material flows like a liquid when sheared but thickens and behaves like a solid when it is allowed to stand.

In literature there are few works dealing with dust analysis in composite materials [7].
It is a common knowledge that the most nocive dust particles are the smallest, and that trimming composite materials produces a great amount of these particles.

So, as the properties of materials are changing with respect to its spatial dimension, the tribological performance of solid lubricant in the metal cutting is a matter of research.
Studies over the years have demonstrated that regardless of the form used, H3BO3-based solid lubricant films can afford low friction coefficients and high-wear resistance to sliding contact interfaces of metallic, ceramic, and polymeric tribo-materials.
Effectiveness of boric acid under actual conditions of metal forming operations such as rolling, forging, and sheet metal drawing and stretching is evaluated with both ferrous and non-ferrous work materials [4].
It can be used in many fields and ushers material science into a new era.

The dynamic modulus of elasticity and the poisson's ratio of roadbed material were defined.
Power Response Experiment Mechanism Analysis The slab track roadbed was composed by many different materials, for example, the graded broken stone, the reinforced concrete, the cement mortar, the rubber spacer.
These materials in the roadbed were mixed uniformly, which have anisotropy and inhomogeneous.

Materials and methods Selection of remote sensing data and vegetation index. 84 MSS, TM and ETM+ data, collected by Landsat satellites during 1973 to 2011, are selected from 115 Landsat data by getting rid of the remote sensing images with thick cloud, large area thin cloud (more than 5% than research area) and stripes due to sensor failure (Table 1).
