Can anyone analyze microstructures? (Steel AISI D2)

[Bruno R SIlva]

I am doing a work in Materials, and we were supposed to do an austemper (bainitic temper) in the steel AISI D2.
I got this microstructures, but i can't recognize what's in it.

Can someone help?

have you tried looking through the asm handbook of metals (i think metallography volume has changed once or twice). 2004 is volume 9. at a glance i would say carbides in a ferrite matrix, but I am not sure about the matrix.

The matrix would be bainite.
