Variation of Strength Characteristics of Titanium Surface Layers Under Magnetic Field Effect

Resumo

In work using micromechanical test method it is determined that the magnetic field (0.6 T) reduces the mechanical properties of commercially pure titanium and their subsequent stabilization. The dependence of the microhardness on the time of the magnetic field treatment is established. We define a linear dependence of the microhardness on the processing time for the value of the induction of the magnetic field of 0.3 Tesla. Magnetic influence with the induction of 0.4 T is characterized by the exponential dependence of the microhardness on the processing time. Established threshold value holding time of 0.5 hour, below which the effect is observed irrespective of the influence of the magnetic field of the magnetic induction. The hypothesis of a magnetic field on the mechanical properties of the surface layers of commercially pure titanium, which qualitatively explains the observed dependence.
