One of my magic systems consists of the ability to magically synthesize a material in a given shape. The material can be any one of the elements from hydrogen all the way up to gold, or one of a small number of molecules (such as water, sugar, and salt). Only one kind of each material can be produced using magic. For example, all iron produced by any iron-synthesis spell will be chemically and structurally identical to one another. When a spell is cast, the material will suddenly spawn into existence in front of the user, with whatever was in the space it now occupies being removed from existence.
When an iron-synthesis spell is cast, the iron produced will be chemically pure (i.e 100% iron, not just 99.99...%) and structurally homogenous. That means the iron's crystal structure will be identical throughout the produced volume. In other words, the iron will have none of the grains, cracks, or imperfections we would expect from iron produced through natural means. From my research I believe the produced iron should be ferrite (as that is the allotrope that is stable at 'normal' pressures and temperatures), but without the corresponding grain structure or dissolved carbon.
With that information, what material properties would be expected of my magically produced iron?
Material properties of particular interest would be strength, hardness, ductility, malleability, and conductivity.
I understand nobody will be able to provide hard numbers as this is a material which cannot be produced in reality, so I would be happy with logically-reasoned comparisons to existing forms of iron.
My Educated Guess
From what I have researched, I think such a metal would be very soft, and also much more brittle than regular iron. This is because, from what I have understood from Steve Mould's video it is grain size that mediates malleability in iron. With no grains and therefore no dislocations, I would expect the material to be less malleable. Additionally, high-purity iron is very soft.
On the other hand, AlexP pointed out such a material would be monocrystalline iron, which apparently has tensile strength well into the gigaPascal range.
