Building materials production has a huge environment impact which is necessary to reduce.
A possibility how to reduce ecological disturbance is to use secondary row materials.
A decrease of metallurgical industry production makes from the energy power industry main provider of secondary materials.

In this paper, fundamental experiment carried out by using modeling material and knowledge about bonding of some separated parts was obtained.
Introduction Industrial products with complex shape and/or different material at low cost have been increased in recent years.
For the same cause, material is considered to be flowed to the underside of rib.
Because too much material flows to the underside of ribs and pushes the rib, it is not extruded while the outer portion is extruded.

Life distribution of fatigue strength of steel materials follows the lognormal distribution or Weibull distribution in general.
Ultrasonic Fatigue Testing Material and Specime.
When the reliability of p= 50% , the S-N curve is commonly fatigue S-N curve, the model of S-N curve is used by the Basquin model[3], the model is expressed as: (8) Where m and C are material constants, S is the stress amplitude loading, N is the fatigue life.

The eddy current technique is also sensitive to defect direction, but it can be applied for inspecting conductive materials only.
The choice of an optimal method depends on factors such as welded materials, joint geometry, and the welding process.

It is indicated that the water dose to the best cooling effect must be equivalent to the amount of water that materials can vaporize and participate in the phase-change heat transfer under certain temperature.
So we need to build experimental platform such as: Simulation of the materials generating cutting heat continuously in practice cutting, feeding heat to one end of the test sample, cooling the other end of the test sample with different water density in cryogenic gas atomization jet cooling, and we should minimize the impact of environmental factors as far as possible , check the changes of the temperature real-timely and transmit it to the Data Acquisition Instrument.
Similarly , when at 500 ℃, 650 ℃ on the nickel-base alloy test sample surface, 4ml/min and 6ml/min water dose can be all vaporized and processed phase-change heat transfer, it is indicated that the best heat transfer coefficient corresponding to materials and temperature must be found for getting the best heat transfer effect.
It is indicated that the water dose to the best cooling effect must be equivalent to the amount of water that materials can vaporize and participate in the phase-change heat transfer under certain temperature.
