The results show that ultra-fine grained materials prepared by this technology possess superior thermal stability. 0 Introduction The ways to improve the strength of carbon structural steel include martensite phase transformation, grain refinement,etc, but the toughness will decrease dramatically when martensite phase transformation improves the strength.
According to the relevant literatures at present, a new technology with the most promising industrialization prospect in SPD of steel materials is equal-channel angular pressing (ECAP), of which the research field is only within low-carbon steel.
The size of ferrite grains in carbon steel is refined to submicron level quickly and uniform distribution of carbides in ferritic matrix is realized. 1 Test material and method 1.1 Test material The hot-rolled steel 1045 bar was chosen as the test material, of which the size was φ10 mm×100mm.

Material and Methods The main instruments and reagents.
There were different affinity abilities between heavy metal and different univalves, and there was different retaining time after combination with some endogenous materials, and which cause the different accumulation of heavy metal in different kinds of univalves.

Eco-materials based on renewable resources have attracted growing attention.
Flax is one of the major natural materials with great potential of application in the composite field.
In this case the strength deterioration of the materials might be caused.

Introduction Extrusion as a technological process is used to produce building components with constant cross sections from materials such as aluminum, copper, stainless steel and various types of plastic.
Material modeling To model the extrusion process, a material model is required to describe the material behavior which is controlled by various microstructural processes.
This material model is required to describe the material behavior which is controlled by the presented microstructural processes.

Recycling, recovery and improvement of properties of ceramic tile manufacturing by adding two types of glass in clay mixtures CHEMANI Halima1,a. 1Department of Materials Engineering, Faculty of Engineering Sciences, University M'Hamed Bougara, Boumerdes, 35000 – Algeria.
It should be noted that glass and ceramic are materials interrelated, because of their origin in particular.
Thus, number of industries uses it in the manufacture of various materials.
The grinding of materials was carried out in ball mills - grinding media: sea pebbles.

The base materials (cracking tube, weldolet), and the weld were analyzed regarding the chemical composition through energy-dispersive X-ray spectroscopy (EDX).
In most applications, Incoloy 800HT alloys are welded using as filler materials the ERNiCr3 alloys, specifically used to minimize hot cracking.
