Introduction Low-activation materials for fusion reactors have received much attention in the past decade because of their importance for environment and nuclear waste management.
The main advantage of using heavy ions is the high displacement damage production within a short term, and therefore enables some screening test on microstructure in candidate materials.

It is the optimization and integration of several ballastless track, and its main innovations include the following: to change the traditional displacement restriction mode of slab track, to expand the filling layer materials under the slab, to optimize the structure of the track slab, improve the elasticity of track, and perfect the design theory system, etc. 1) III type slab connect the self-compacting concrete (internal reinforced net)and track slab into compound structure by setting two u-shaped steel under the slab, and its structural integrity is good.
Prevention measures of CRTS III track slab cracks Optimize raw materials 1) To reduce the hydration heat, we should use low early hydration heat of cement, whose mineral composition and fineness modulus is appropriate. ①Reduce content of C3A and C3S in cement clinker, use moderate heat Portland cement and low heat Portland slag cement in the construction commonly; ②Without affecting activity of cement, we can try to make an appropriate increase in the fineness of the cement because cement fineness would influence the hydration exothermic rate. 2) Try to increase the size of coarse aggregate.
