In recent years, the functions of synthetic fiber as a reinforcing material of concrete has gradually been recognized, i.e. the main contribution of low dosage synthetic fiber to the improvement of comprehensive performance of concrete is anti-cracking and toughening rather than reinforcing[3].
This promotes the development of production technology of fly ash concrete and its popularization and application in other projects. 1 Overview of the Test 1.1 Raw Materials of the Test The cement used in this test is P.O 42.5 grade ordinary Portland cement manufactured by Zhengzhou Shangjie Cement Plant.

Friction stir welding is a solid-state process, which used frictional heat to blend the two joining materials together and create a metallurgical bond.
Hammer peening involved plastically straining a material using a hand held peening tool with an oscillating tip, which produces small, round indentations on the surface.
The interface between the weld nugget and the TMAZ corresponds to low hardness regions because the original structure in this region is over aged and there is not enough solute left in the material.

Influence of solution treatment on the microstructure and mechanical properties of an deformed Al-12.7Si-0.7Mg alloy Liu Fang1,a, Yu Fuxiao1,b, Hu Ke1,c, Zhao Dazhi1,d, Zuo Liang2,e 1School of Materials and Metallurgy, Northeastern University, People’s Republic of China 2Key Lab for Anisotropy and Texture of Materials (Ministry of Education) ,Northeastern University, People’s Republic of China aliufang@smm.neu.edu.cn, bfxyu@mail.neu.edu.cn, chukee12345@126.com, dzhaodz@smm.neu.edu.cn, elzuo@mail.neu.edu.cn Keywords: Deformed Al-Si alloy; solution treatment; Microstructure; mechanical properties Abstract: Deformed Al-12.7Si-0.7Mg alloy was heat treated for different solution treatment.
The results show that a short solution treatment time of 30 min is enough to achieve a high and homogenous Mg2Si concentration for a material with a fine microstructure.

Conventional drying usually involves the use of hot air combustion gases, or super heated steam, which heats the materials by convection and conduction[2].
In this process, microwave penetrates inside the material and heats materials with high dielectric constants[3].
Materials and methods Xilingol lignite was used in experiments (Table 1) and all samples were crushed and sieved to 5 size fractions (-0.3, 0.3-0.6, 0.6-1, 1-3, and 3-6mm).

The ESO process begins with a full design domain and the parameter rejection ratio (RR), evolutionary rate (ER) was used to control the deletion of the materials.
In addition, the inefficient materials in the optimized design domain are only allowed to be removed through deleting criterion but not allowed to be added at the same time.
The mechanical properties of the material are assumed to be E=210Gpa, and ν=0.3.
Therefore, the material of pier gets the maximum use.

Even edges at the same level do not necessarily cut if preceding edges have already removed the material.
Experimental Approach The workpiece material was selected to be Inconel 600 series nickel-based alloy.
The material cannot be used directly on the grinding wheel as separation after curing usually results in the destruction of the wheel.
The peak-to-valley parameter S10z does not vary much and in-fact initially increases suggesting that base material is removed and thus exposing the grains more.

Introduction High titanium slag is one of the most important raw materials of titanium dioxide.
Thus, through the heat treatment at 1073K, the complex solid solutions of high titanium slag with capricious properties can be mostly changed into rutile, which is a material with stability properties, high hardness and large density.
