Structure Phase

Using transmission electron microscopy methods the layer by layer analysis of the bulk hardened superior quality rails is carried out and the quantitative parameters of structure, phase state and defect substructure gradients are established. It is shown that the interface boundaries globular cementite particles-matrix are the possible places of microcracks initiation.

The Impact

Experimental results on the impact of pulsed ion beam with parameters the pulse duration 80 ns, energy of 200 keV and current density 120 А/сm2 , pulse energy ~ 1,5 J/сm2 on the alloy Zr1Nb on structure – phase state of the alloy of zirconium Zr1Nb. It is shown that such irradiation leads to changes in the structure of the surface and the hardening of the material.

Structure Phase

Mechanical properties of specimens of Armco-Fe and a wide range of structural steels in various structural conditions have been studied. It has been found out that the use of different strengthening mechanisms leads to a decrease in plasticity parameters with different intensity at the uniform and localized tensile stages. Analysis of the tensile engineering and true curves showed that splitting a uniform stage into linear and power-law periods gave the best analytical description of experimental tensile curves with R2 = 0.99. The plasticity parameters on linear and power-law periods that are sensitive to changing the initial structure-phase state of the studied steels are proposed.
