Název v původním jazyce

Influence of aluminium on retained austenite stabilization during thermomechanical treatment of low-alloyed TRIP steel

Popis výsledku v původním jazyce

TRIP steels are multiphase steels. In standard TRIP steels cementite precipitation during bainitic transformation and retained austenite stabilization are carried out mainly through silicon alloying. Silicon at higher concentrations causes problems withsurface quality in some applications. One of the alloying elements being taken into consideration for silicon replacement is aluminium, whose addition not only restricts carbide and pearlite formation during bainitic transformation, but also increases formation of acicular ferrite. A lower value of solid solution hardening and the increase of the Ms temperature represent the disadvantages of aluminium addition. Thermomechanical treatment with various parameters of bainitic transformation was investigated on the 0.26C-1.5Mn-1.3Al steel with the aim of determining how aluminium affects structure development, retained austenite stabilization and mechanical properties.
