Influence of micro-alloying on the phase transformations in cast manganese steels
Petr Motyčka, Jaroslav Drnek, Libor Kraus
Strokovni članek
Oznake: cast manganese;steel;microalloying;transformation temperature;cooling rate;microstructure;
The influence of m icro-alloying on the course of phase transformations in cast manganese steel with 0.15 % C and 1.2 % Mn was studied. Vanadium, niobium and titanium were added as micro-alloying additions. Changes in the A[sub](C1) and A[sub](C3) temperatures as well as the austenite transformation ...
