Introduction Concrete is a traditionally-used building material whose crack resistance can be improved by the addition of even relatively small amounts of different types of fibres.
These parameters characterize the tested materials in more detail and proceed from the combination of linear fracture mechanics principles and the concept of cohesive forces acting on the faces of the fictitious (effective) crack increment.
Thus the inclusion of fibres could not postpone the crack initiation in the material.

Ni-Resist is one of the most widely utilized materials in corrosive environments, due to its excellent resistance to corrosion by alkaline fluids and dilutes acid, especially for chloride containing media.
Despite its successful application in different corrosive environment, this material still being investigated and tested to obtain a better performance in corrosive environments [2].

Rail damper is a new technique designed based major on vibration absorber for railway noise and vibration control, which is a vibration damping and noise reduction installed in the light of rail transformation, and consisted by a damping materials and restraining plates on the surface of rail.
The frequency range and its working temperature are around 10Hz-20KHz and -30℃~51℃, respectively, with a rather high strctural loss coefficiency of 78%, which is quite higher compared to other rubber materials of only 2%~5%.
The physical and mechanical properties of damper material are shown in Tab. 1.

If ductile cast iron is transformed to bainite single-phased structure through austempering treatment, its ductility goes down considerably compared to cast materials composed of ferrite-pearlite.
The tension and strength of each material are presented in Table 2.
In full-ADI, static strength was enhanced considerably compared to the cast material, but ductility decreased a lot.

The crystallization of amorphous alloy can make structure and properties of materials greatly changed.
Therefore, the behavior of crystallization of BMGs is significantly important to determine the forming ability of BMGs and prepare the new materials [10].
