So that metal materials using incremental forming to process mainly concentrated in aluminum, copper, and 08 steel, titanium alloy and other difficult-forming materials were rarely reported in literatures[4-6].
The material parameters were shown in Table 1 and Figure 2 (Datum from materials library of DYNAFORM software).

The test results shows all the three materials were proved satisfied with bearing capacity increasing request.
The mature reinforcement methods used today are structure member strengthenting with R.C , structure member strengthenting with R.C ,structure member strengthening with externally bonded  reinforced materials,compression member confined by reinforcing wire,structure member  strengthening with externally applied prestressing,etc.[4,5,6].Three reinforcement materials with steel plate, epoxies resin sheet, and glass fiber sheet adhering to failed RC beams were compared by experiments in this paper.
Reinforcement Materials and Scheme The type of reinforcement plate is Q235, 3mm thickness, the bottom area of the reinforcement beam increases 3.0cm2; the thickness of epoxies resin sheet is 5mm, 4 cloth 5 glue boards; the width of glass fiber sheet is 50cm.
Adhesive glue used is epoxy structural adhesive .The reinforcement scheme of various materials is shown in Tab. 1.

A new unburned brick was prepared from the Ti-bearing blast furnace slag as an aggregate and PVA modified by epikote as cementitious materials.
Therefore, epikote-modified PVA [9-10] is used as cementitious materials to prepare slag brick with the virtues of high quality and low price.
Experimental Materials. polyvinyl alcohol (1750 ± 50) , epikote, auxiliaries are all purchased from Sinopharm Chemical Reagent (Shenyang) co., Ltd.
Fig. 1 The relationship between the compressive strength of slag brick and addition amounts of raw materials Summarizing the study, the optimized mass fraction of raw materials for the preparation of slag brick should be 6% of epikote-modified PVA, 6% of auxiliary 1, and 10% of auxiliary 2.

To effectively detect the defects, the dispersion characteristics and multimode of guided waves in the plate are studied by the disperse simulation software, and the variation of dispersion curve is analyzed by the geometric parameters and materials of plate.
Fig.1 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 1mm Fig.2 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 2mm Fig.3 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 3mm Fig.4 Dispersion curves of Lamb wave propagation in steel plate, the thickness of plate is 4mm Material impact on Lamb wave dispersion curve Lamb wave dispersion curves for a plate of the same thickness have essential differences due to the difference in materials selecting, the density of the material, the longitudinal velocity and shear velocity of the guided wave propagation.
Lamb wave dispersion curves for a plate of the same thickness vary from each other due to the different physical characteristics of different materials.

Structure analysis Crystal structure of materials was determine by XRD technique.
The statistical distribution of values are shown in Figures 4b, 5b and 6b with 10±2 nm, 2.5±0.4 nm and 8±1.7 nm for as synthesized ZnO and ZnO2, and for ZnO obtained by annealing, respectively; the last two materials have narrow size distribution, confirming the material synthesis methodology for both materials are adequately.

However, the process for preparation sodium ascorbate mentioned above has some defects such as long reaction cycle, low conversion rate, high cost of raw materials and poor quality of crude sodium ascorbate product.
Experimental procedures At first, put 130 gram 2KLG and 1000 milliliter methanol into a clean four-mouth flask, then add 5 gram concentrated sulfuric acid and mix the materials.
In addition, the use of sodium carbonate reduces the cost of materials and has good potential applications.
