Making Sense of Oxides in Hot Working

[darkelf]

Hello,

I'm working on material transfer during hot working. My chemistry isn't to good. Could anyone explain if different oxides give different properties to different materials. Say MgO, would it give a different property to Aluminium from that it would give say Steel?

If so is there anyway I can find out what property an oxide gives as in is there like a catalog?

Thanks

Oxides will be chemically different in different alloys, but they generally have the same behavior - dispersion strengthening.

Thanks, but is it possible for oxides to make a metal brittle? Say Magnesium oxides in Al?

Sure. At some level the oxides are not beneficial but detrimental to the desirable properties, such as strength and toughness.
