      7/ well, the way that the actual IRL eutectic chart works is that temperature is measured on the vertical axis and percent carbon / percent iron on the horizontal axis, and as you heat and add carbon to iron it moves around the 2-D phase space >>> https://twitter.com/yorrick09/status/1262742019266342913 …

      9/ and the C are captured in the lattice in places that they wouldn't normally be, and you get sort of a Buckminster Fuller "tensegrity" structure going on, and a bunch of Fe cages clamped tight around C balls in the center are more rigid than floppy empty Fe cages

      10/ and, TLDR, this is why one hardens steel by plunging it into water, or oil, or whatever. HOWEVER once you do this the steel is too hard and can shatter if dropped, so you want to warm it up a bit (to "straw yellow", usually) and let a bit of annealing happen, >>>

      11/ The eutectic chart I posed before is just the simple Fe / C chart, but this - as advanced and scary as it is - is just baby stuff compared to the full set of alloys that are out there. So, anyway, just as chemistry evolved out of alchemy, so did material science >>>

      13/ scientists understand a lot of things. SO ANYWAY the original reference I was making was to a fantasy world where maybe alchemical-blacksmithing is well understood, to the point that eutectic charts exist... BUT ... there are "hidden islands of stability" or something

          I often make the same point about Roman concrete. The Romans probably discovered this by accident or trial-and-error, and had little to no understanding of why it worked, or how. But they knew that it did. 1/?

          And that practical/empirical knowledge often precedes scientific knowledge in this manner. Humans stumble into things, and then only later through experimentation and observation, discover the underlying mechanisms.

          I love the "hidden islands of stability" concept, particularly since these are hypothesized to exist among certain isotopes beyond what we have currently made.

          Also, to my knowledge, that has not been done. Tolkien had mithril, Sanderson had atium, Star Trek has dilithium, etc. So, fictional metals are frequently used but ulyour idea, so far as I know, is unique
