Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Why Austenite grains in steel show much more twinning than ferrite grains?

It is oftentimes said to be a distinctive metallographic trait that differentiates a fully austenitic and a fully felly ferritic steel without etching that might distinguish between two. Why...

How Can I bring as much common elements in steel as possible to calculate stable phase(s) in OpenCalphad?

As I was tweaking step-by-step OpenCalphad6 Macros step1.ocm involving phase and thermal property calculation of a High-speed steel, I could not incorporate more than 6 elements in the steel...

For Carbon-emission free steelmaking by electrolysis with nonoxidizable electrode in EAF, what would be electrode material?

While CCS can be employed along with a conventional Carbon-efficient EAF steelmaking process (especially from iron ore) or even Hydrogen or hydrocarbon can bee passed through central electrode,...

What are the factors on which exchange current density of an electrode depends, and how can they be predicted?

While surface roughness is an obvious factor, this is not what is exactly asked. Rather, periodic variation of exchange current density (of an electrode) with solution chemistry (of electrolyte)...

What are the thermodynamic and kinetic similarities and differences among dendrite formation during solidification of metals, ceramics and polymers?

Basic dendrite formation of metallic alloys are explained by thermal and constitutional degree of supercooling and most-supercooled band of liquid somewhat ahead of solidification front that...

Is it possible to economically reuse the heat content of water vapour that is generated during quenching of continuous casting of steel?

A huge amount of water is evaporated to cool down and solidify the liquid metal strands coming out of bottom of CCM mould. The steam contains significant latent and sensible heat energy, besides...

Why it is not permissible to correct all 5 classical optical aberration (spherical, chromatic, coma, astigmatism, curvature of field) simultaneously?

When first order paraxial optics is expanded to third order optics (i.e. sin x~ x-x3/3! instead of sin x~x) , these 5 optical aberrations result in. What is the rigorous mathematical proof that,...

Is it possible to prepare clay minerals by mixing pure oxides of required elements? What would be theoretical difficulties with it?

Practically this is not at all necessary. But theoretically, would hydrous/hydrothermal synthesis be enough (like mix 1 mole alumina gel and 4 mole silica gel and gently heat) or would it require...

Aranyak Chakravarty

You need to use User-Defined Functions...specifically the DEFINE_PROFILE module. Refer to the UDF manual for details.

Sidhartha Bhowmick

Thank you Mr. Aranyak.

Do you have any that kind of UDF? It would be helpful for me. I am not expert to write UDF.

You can easily write following the example given in the manual. The manual is easily available on the internet.
