Metallurgy Matters: Carbon content, steel classifications

Aug 28, 2003· And while there are steels that have up to 2 percent carbon content, they are the exception. Most steel contains less than percent carbon. To put this in perspective, keep in mind that's 35/100 of 1 percent. Now, any steel in the to percent carbon content range can be hardened using a heatquenchtemper cycle.

Anisotropic Morphological Changes in Goethite during Fe2

When goethite is exposed to aqueous Fe2+, rapid and extensive Fe atom exchange can occur between solidphase Fe3+ and aqueous Fe2+ in a process referred to as Fe2+catalyzed recrystallization. This process can lead to the structural incorporation or release of trace elements, which has important implications for contaminant remediation and nutrient biogeochemical cycling.
