| > That's not an undisputed fact. We can produce steels today with much better metallurgical properties by design. Japanese steel at the time used the folding technique to overcome low carbon content. Thats all my point entailed. And as to what enthusiasts think, all I can counter with is the audiophile community. I wouldn't take their view without some salt especially without some comprehensive analysis. Steel from Spain at the time was also vastly superior to the steel being used in Japan. Ref:

The material and mechanical properties of samurai swords (Japanese swords), made using a traditional steelmaking technology (tatara), are investigated experimentally. The quality of these swords appears to be low because of the presence of a large number of inclusions, including oxide- and phosphorus-based structures; however, their mechanical properties are relatively good because of their fine-grained structure and high residual stress. endquote Also, take the metallurgical properties of turbine blades, there are alloys we can only recently produce based on analysis of bonds between the atoms. While its posssible a past civilization could have come up with these alloys, the neither needed them, and lacked the requisite knowledge to make them. And the roman cement was largely a product of materials. Aka volcanic ash. We lost it only in that the inputs were largely lost. But this all digresses mostly into arguing analogies which is a bit of a rat hole. |
