To protect concrete from freeze/thaw damage, a number of research results about the factors affecting the material performance during freeze-thaw are reported.
Nano-particles possess excellent physical and chemical properties.
Multiple studies have shown that even small dosages of NKC can improve the physical and mechanical properties [3,4], and microstructure [5,6] of cement-based materials.
Physical, mechanical properties were conducted on the concrete with NKC particles compared to the control samples during the freeze/thaw cycles.

Consequently, the reduction of tool wear during milling aluminum alloy can be mainly attributed to the improvement of mechanical properties of carbide tool materials after pulsed magnetic treatment.
However, this approach has not been widely applied yet, since the mechanism of magnetic treatment of tools is not clear and treatment results are affected by many factors.
In order to investigate the effect of pulsed magnetic treatment on the mechanical properties of materials, a pulsed magnetic treatment system was designed and produced in our previous work[5].
In minor flank area, as the friction action between tool and workpiece is a main factor, the decrease in minor flank wear can be mainly attributed to the improvement of material mechanical properties of tool materials after pulsed magnetic treatment.
