![]() The average Rockwell B hardness of 24 meterorite samples is 81 while the average from 53 bridge components is 58. For a comparison, we can use this study of wrought iron sampled from 10 bridge built in Massachusetts in the 1800s. A study of 22 siderites (Iron-Nickel meteorites) reported on their hardness in Table 1 here. A harder blade will cut through a softer one (or wood or bone) without getting blunted.īoth these alloys have a hardness advantage over regular iron. That is, when a force is applied, how resistant is the material to deforming. Hardness is the resistance of a blade to strain. The melting point of both kamacite and taenite is not significantly different from iron, so normal, time-period appropriate methods of swordmaking would be valid. The crystal can be directly worked into a sword via the normal methods. There is no longer any need to smelt to mix the alloy. Finding these crystals means that you have found a pre-mixed alloy. A kamacite crystal listed in table 1 here had dimensions of 0.92x0.54x0.23 meters, and a mass of 303 kg plenty of material to make a whole batch of swords. Kamacite, in particular, can form massive crystals. Taenite's composition is from 20% to 65% Nickel. Kamacite's composition is in the 90:10 to 95:5 Fe:Ni range. Kamacite and Taenite are both Iron-Nickel alloys found (on Earth) only in meteorites. One I hope I will not get, but one I can accept if that's the case. Note: Well described and proven impossibility of such meteorite iron also counts as an answer. If tech required is sufficient to make modern alloys, it is no-go. Last but not least, it must be possible to actually forge it using medieval techniques, and it must be impossible to forge something better or even similar using available technology and no meteorite iron.Basically, anything that would make clearly superior swords or armors. Qualities I seek are resistance to breaking, edge retention, resistance to chipping/notching, ability to forge it thinner, et cetera.Only similar enough that calling it "meteorite iron" or "star iron" would seem justified. Of course, it does not have to be pure iron.By numerous enough above I think amount sufficient to equip heroes if the quality would be legendary, or small armies if it would be barely "very good".Could-be-meteors that don't really fall on Earth but are found or suspected in our Solar system are strong second best.Meteors that actually fall on Earth are best.Meteors that could form in the solar system with an Earth-like planet, if there is a way to make them numerous enough.An Earth-like planet with humans or humanoids indistinguishable from humans.What changes to reality, especially star system, I need to make? What I'm asking here is how to make meteorite iron superior, in a medieval setting, without magic?. Probably from Volo's Guide to All Things Magical (ISBN-13: 978-0786904464), via this site. Now where is my armor?"Ĭold iron is iron found in a pure state (either meteoric iron or an especially rich ore) and is forged at a lower temperature to preserve its delicate properties. ![]() You might as well take him away" – indicating Pantalaimon – "and replace him with a doll full of sawdust. ![]() A bear's armor is his soul, just as your daemon is your soul.
