Abstract

The complex study of the possibility to obtain AISI 304 steel with increased resistance to radiation has been carried out.  Yttrium thermodynamic interactions with AISI 304 steel liquid melt was studied. The possibility of introducing yttrium oxide into the liquid metal matrix is evaluated. Experiments were conducted to obtain AISI 304 corrosion-resistant steel prototypes with the yttrium oxide introduction into the liquid melt. The blanks were obtained by casting on the horizontal centrifugal casting machine.  The micro hardness studies of samples showed that samples obtained with the yttrium oxide introduction have lower gradient of the cross-section hardness index. Microstructures are presented to reveal inclusions formed by yttrium oxide in the casting body.
