Abstract:The structural features and phase composition were examined in near-surface layers in samples of Al-Mg, Al-Cu-Mg alloys and commercially pure titanium obtained by plasma cutting using direct current straight polarity (DCSP) and direct current reverse polarity (DCRP). It was found that the flows of molten metal carried away by the gas stream from the cut cavity during cutting form molten and heat affected zones, whose structural morphology, phase composition and thickness depend on both the selected material an… Show more
