Because it can not only increase productivity, but also can reduce the loss of the workpiece and save raw materials.
With the development of industry modernization, the forging precision and forging velocity are requested more and more high, Because it can not only increase productivity, but also can reduce the loss of the workpiece and save raw material [2-3].

Various kinds of micro-alloy copper and copper alloy materials are applied in the production of electric components which have wide range and a great diversity of equipment mode.
By combining form of organization and characteristic parameter, make a distinction of the metallographic structure characteristics of short circuited melted mark between the two materials.
In order to make comparison analysis of short circuited melted mark of the two materials, the thesis selects the brass strip in the power supplying socket and 1.5mm2 sub-thread copper conductor for the short circuit simulated experiment.
Select typical figures of the metallographic structure and form the short circuited melted mark metallographic phase of diverse copper alloy materials under different current conditions.

From the obtained results there is not drastic difference in the crystalline phases between the obtained materials Dt-100 and Dt-300.
Recently, there are many interests in adsorption processes using low cost and available materials for dyes removal.
Materials and methods.
The material obtained was noted Dt-100.
This study has allowed us to show that it is possible to substitute existing high cost adsorbent materials (like activated carbon) by effective and low cost ones.
