Mechanism of Precipitation of Carbides during Deep Cryogenic Processing in 1.2542Tool Steel

What is it about?

Control and prediction of size, content, and distribution of secondary carbides provide the possibility for achieving optimum structural properties. In this research, theoretical study has been done by thermodynamic phenomenon. Second, nine sets of 1.2542 tool steel specimens have been deep cryogenic processed and then tempered. After that, experimental study has been done by double deep cryogenic processing. Result was, during tempering, new carbides precipitated around the primary carbides (located in the grain boundaries) obviously.

Why is it important?

To expand science in the field of microstructures, it is inevitable to be aware of the formation and growth mechanism of secondary carbides induced by deep cryogenic processing.
