Phase chemical elements distribution in complex-alloyed white cast iron

The microstructure and phase elements distribution in modified complex-alloyed white cast iron is studied. It is found that in as-cast condition the cast iron contains carbides MeC (spheroid), Ме7С3 and Ме3С; the matrix consists of troostite and martensite-austenite areas. It is shown that vanadium and chromium can replace each other in carbides MeC and Ме7С3. When 10 % of vanadium is dissolved in carbides the inverted eutectic “austenite+ Ме7С3” can be crystallized even at low Cr content in cast iron
