through super-hard wear-resistant surface electrode surfacing D707 in Low-carbon steel. We have analysis the effect of welding process parameters and post-weld heat treatment process on low carbon steel surface hardness of cladding layer. The experimental results show that: after quenching hardness value no significant change; But after annealing the hardness value decreased and after annealing the crystal grain of the underlying tissues uniformization become tiny. micro-hardness testing is carried out in the weld cross-section, we have find out that from the base metal to the cladding layer the surface hardness values is getting higher and higher, while the indentation is getting smaller and smaller. Because hardness is a measure of wear resistance materials, thus it can indirectly show that when low-carbon steel surface electrode in the super-hard wear-resistant surfacing welding layer, it can improve the surface hardness of low carbon steel and improve wear resistance of low carbon steel surface.

In the paper, the relationship between the grain size and fatigue life are studied. To specify the initial and short crack propagation life of low carbon steel material, three methods are used in the simulation. At first, the K. Tanaka’s model is introduced to calculate the fatigue life of a grain. Then, the Voronoi Diagram is used to generate the microstructure of grains. At last, a criteria to specify the short crack is proposed. Based on these methods, the numerical simulation is conducted. With the help of the process, the grain sizes are generated randomly in order to specify how grain sizes effect fatigue life. The computational results are in good agreement with the experimental data. The results show that the randomness of fatigue life is closely related to the randomness of grain sizes.
