JNot so.
Steel does not go from solid to liquid [can be poured] instantly, it happens over a range of about 100 degrees F. First it starts to loose its shape, then it becomes like a glob and finally it becomes runny, much like lava. We can observe lava running very fast in lava tubes when it is very hot and very slow when it is almost solid again.
I love being "lectured" by C7.
FFS! I'm almost thought about posting something that would give me a periodic ban here because of his statement, but that wouldn't be beneficial to anyone. The iron-carbon phase diagram has been burned into my memory so much so that I could draw the damn thing from memory aged 21. Hardly adolescent.
I said
I really dislike the word "molten" in the 9/11 context. Steel is either solid, solid plus liquid or liquid.
And yet he thinks that his above quote has somehow disproved what I said, except of course he uses the fantastic metaphors glob, runny and lava.
Somehow he thinks that I don't know that steel melts over a temperature range even though I alluded to that in my post.
What is it with truthers and their lack of reading comprehension? Sheesh.
In fact an air cooled steel of ASTM A36 composition , based upon a 0.25C wt%, (therefore a hypo-eutectoid), using the Fe-C equilibrium diagram, upon heating from room temperature, actually undergoes a transformation from pearlite and ferrite to ferrite and austenite at approximately 723°C. The full transformation to austenite occurs at the A3 temperature (approximately 840°C). At around 1480°C austenite (solid) will be present with a liquid. At around 1493°C the peritectic is encountered and the remaining austenite will transform to delta ferrite (solid) and liquid. Around 1510°C the alloy will be fully liquid.
So you are approximately correct stating that liquid is present with solid over a 100°F range. Well done. Now I'd be more impressed if you could explain why I chose an air cooled steel as opposed to a quenched one.
Seeing as it's bank holiday Monday I shall be off to teach my grandmother how to suck eggs.
