With semicrystalline materials a layered skin-core structure is formed during the filling phase.
The rapid manufacturing usually includes the use of non-metallic materials, i.e. epoxy composites with metallic fillers [14, 15].

Effects of cryogenic treatment on mechanical properties and corrosion resistance of LC4 aluminum alloy Wenda Zhang1, a, Jing Yang, Jingzhi Dang, Yun Liu, Hong Xu 1 School of Materials Science and Engineering, North University of China, Taiyuan, Shanxi, 030051, China azwdno@139.com Keywords: LC4 aluminum alloy, cryogenic treatment, mechanical properties, corrosion resistance.
Thus it has become one of the most widely used structural materials in the aviation industry [1-3].
It has been previously reported that [5-6] cryogenic treatment could improve the microstructures, stabilize the dimensions and prevent the deformation of metal materials [3-6].

In this case, an established link between materials parameters and P-h curves can naturally lead to direct hardness estimation from the materials parameters (such as yield stress and work hardening coefficients).
Materials and Experimental The material used were steel.
Similar agreement has been found in other materials (within 5% error range).

The synthesized Ca2.6Bi0.4Co4O9 ceramic materials have potential application for high-temperature thermoelectric energy conversion.
Developments of thermoelectric materials which convert heat into electrical energy are expected for the efficient use of energy.
The thermoelectric materials should be chemically and thermally stable to utilize waste heats, since they are supposed to work under conditions of high temperature and corrosive atmospheres [1-3].
