The effect of silicon on the tempering behavior of carbon steels is well established by several researchers. Silicon inhibits the coarsening of the cementite and promotes its dissolution. The most significant characteristic of Si which results in its extensive use in TRIP-aided steels is its ability to restrict carbide precipitation during isothermal holding resulting in the desired carbon partitioning to austenite and its stabilization. However, my question is related to a different type of steel, medium-Mn stainless steel.
We have two grades of medium-Mn austenitic stainless steels bearing V, i.e., grade 2 wt.% silicon, and low silicon grade containing 0.4 wt.%.
What is the Influence of silicon content on the precipitation (type, formation efficiency, and size) of secondary carbides in that steel?

The studied steel in that article is bearing a low Si content of 0,4 wt.%, How about the effect of high Si content of 2 wt.%?
