Abstract
The paper presents the influence of resistance welding parameters on the mechanical properties and structure of joints of the unalloyed steel rail and high-manganese crossover. As the spacer Cr-Ni austenitic cast steel with decreased austenite stability was used. The results show, that the austenitic cast steel with metastable structure of austenite provide to high strain hardening of spacer deformation during operation. The high increase of hardness is the result dislocation hardening and the transition of austenite into martensite. The content of ferrite &delta and martensite was measured by metallographic method and verified by X-ray diffraction phase analysis. Moreover, it was shown that to high welding parameters causes the cracks in HAZ of manganese iron cast and in the spacer near to fusion line with unalloyed cast steel. The reparation of cracks can be made by welding methods.
