The semi-solid forming process has been developed to overcome the technical, economic, and environmental limitations being caused by using light alloy materials.
They are the processes that form the materials in which primary α-Al phase particles can be controlled by their rheological conditions.

The amount of total chloride ions in concrete used as repair materials were measured under immersion conditions.
Structural concretes damaged by corrosion are often rehabilitated by applying repair materials.
When the concrete used as a sort of repair materials, the addition of mineral admixtures may be a way to solve this problem.
Experimental details Raw materials used.

Auction Mechanism and Methods for Heterogeneous Goods Such as Multiple Polymer Materials Congjun Rao College of Mathematics and Computer Science, Huanggang Normal University, Huanggang 438000, China cjrao@163.com Keywords: Multi-object auction; heterogeneous goods auction; Polymer Materials Abstract.
In this paper, the auction mechanism and methods for heterogeneous goods such as multiple polymer materials (rubber, plastic, polymer fibre, adhesive, polymer coating) is investigated.
Introduction In the market trade, the buyers often encounter high polymer materials procurement, such as the rubber, plastic, polymer fibre, adhesive, polymer coating and polymer matrix composites.
We can use the auction method to procure this kind of polymer materials.
