Energy Input Requirement

Energy Input Requirement

Energy Input Requirement

(OP)
My question is quite basic I think.  I am designing an apparatus whose function is to work metal by means of steam and or abrasives.  I am trying to figure out the required energy input so I can figure out the working pressures and temperatures that I will need to design for.

I believe that the 'modulus of toughness' is the property that would give me a good idea of energy requirements to cut or mill certain metals using the method described above.

Also, In the MERM it it has a generic 'Failure Energy versus Temperature' figure (pg 46-15 upper-left).  Where could I get a hold of some similar metal-specific charts? The reason being that I will be working at approximately 1100-1200 degrees and I know that such a working temperature would obviously significantly affect the energy input requirement that I would need to design for.

Lastly,  If it is assumed that I am working steel at a temperature of say 1100-1200 degrees (steel part to be worked submerged in water lets say) as long as I stay well below the  1300+ Fahrenheit transition temperature for steel, it shouldn't affect the composition much if at all right?

Am I correct in my assumptions?  I want to make sure that I am on the right track.  If I am not correct could you point me in the right direction and explain to me why I am not correct?  Thank you very much for your time and help in these matters.

RE: Energy Input Requirement

Might want to try the machine and machining or Metal and Metallurgy subforums.
