Abstract
1. Adding vanadium and titanium to Fe−C−Mn−Cr-alloy leads to the formation of special cubic carbides and redistribution of chromium between the phase components: its content in the metal base increases. The distribution coefficient for chromium between special carbides and austenite decreases from 4.2–4.8 to 2.9–3.7. 2. Addition of vanadium and titanium promotes an increase in the electrode potential for alloy 300Kh27G11 from (−0.3) to (−0.2) V and a reduction in the corrosion rate in sea water from 0.052 to 0.040 and 0.032 mm/year respectively. 3. Alloys based on the system Fe−C−Mn−Cr containing vanadium and titanium are promising materials for preparing cast articles which exhibit high corrosion resistance in sea water.
