It's a matter of semantics. If a steel beam is folding, it is flowing, however slowly, so "technically" it's molten. But molten is normally used to describe metal that is visibly flowing or dripping.
You haven't the slightest clue what you are talking about.
I suggest that you go look up the definition of the words "yield", "plastic deformation" & "creep" in an engineering dictionary.
Every one of those definitions can appropriately apply to "a steel beam folding, however slowly". In none of those cases is the metal flowing or melting.
Only the truther dictionary says:
yield: see melting
plastic deformation: see melting
creep: see melting
___
In each one of the following pictures, there are objects that have been formed by humans into specific, geometric shapes and then a portion of those objects have melted.
Let's see if you are astute enough to be able to distinguish the difference between "pre-melted" and "post-melted".
Let's see if you are sufficiently literate to put into words the specific geometric criteria that identifies the "not melted zone", the "melted zone" & the "transition zone" in each picture.
I'm fairly sure that any competent 7 year old child could do this easily.
And one last, famous one:
Now, let's see if you can find some steel columns that match your own distinguishing criteria.
Let's see if you're as astute as a 7 year old.
This should be good...
