The contacting shoulder and pin surface make the workpiece materials to soften into the plastic state, then the materials flow around the tool pin from the front to rear, where it consolidates and forges under the confining pressure [3].
The depth of tool penetrating into workpiece was constant, the vertical force acting on the material decreased with the materials became softer.
Comparing the three materials, the vickers hardness of TC4 was highest, and the vickers hardness of T2 was higher than LY12.

Fig.1 Crack Width of Groutable of Different Materials (XU Xingliang, 2007) The firstly, the chemical grouting which has good toughness and adhesiveness features can generate net framework in argillaceous surrounding rock after it consolidated, the strengthened argillaceous surrounding rock can keep high residual strength and good bearing ability even large deformations take place under overload, so the argillaceous roadway can be easy to be controlled.

Cathode materials, traditionally used in industries, such as LiCoO2 , LiNiO2 , LiMn2O4 have pretty good electric performance, but expensive raw materials and toxic cobalt make them unsuitable for large-sized batteries production [1].
The cathode material LiFePO4 (LFP) is the best studied material among cathodes of the polyanion type (class of materials with tetrahedral structural unit (XO4)n-, and its derivatives (XmO3m+1)n- where (X=P, S, As, Mo, W), connected with the polygons MOx, where М is transition metals) [2-4].
However, as many other similar cathode materials of the polyanion type, Li2FeSiO4, still has insufficient conductivity (6*10-14Cm/cm) [8].

Fig.1 Heat storage materials with expanded graphite Fig.2 Scanning electron microscope photograph of the expanded graphite After differential scanning calorimetry, the transition temperature of phase change materials with expanded graphite is 58.544 ℃, phase change enthalpy is 307.762 kJ/kg.
The transition temperature of phase change materials without expanded graphite is 63.71 ℃, and the phase change enthalpy is 311.997 kJ/kg.
The reason is that the expanded graphite has a high thermal conductivity and heat storage and release rate of the composite phase change materials is improved, in transfer process.
Phase change materials were made into a square plate, size 260 mm× 260 mm× 20 mm(Fig. 7).
