Zusammenfassung:Title screen
The results of structuralphase conversions in a zirconium coating–silicon substrate systemtreated with lowenergy highcurrent electron beams (LHEBs) are presented. It is revealed that the action ofLHEBs with energy densities of 8–10 J/cm2 leads to the formation of a eutectic layer containing clusters witha characteristic size of 40–50 nm (the melt of ZrSi2 and silicon) at the zirconium–silicon interface. After theenergy density reaches 12 J/cm2, silicon dendrites and regions of silicide crystallites are formed in the surfacelayer 20–30 µm thick. Data on the characteristic sizes of dendrites and eutectic clusters have made it possibleto perform numerical estimation of the surfacemelt overcooling (12–25 K), the temperature gradients(3.7 Ч 107–1.6 Ч 108 K/m), and the interphase boundary velocity (0.8–3.2 Ч 10–4 m/s).DO
