I read in a newspaper, that The Danish Technical University (DTU) had developed a method to make brass/bronze (unfortunately I don’t remember whish it was) as hard as steel. They cast it under pressure, and the metal got harder and harder the more pressure they put on, but only to a certain point – they could not get it harder than steel. Is it at all possible that users of these metals could have know anything about this. I doubt it, but if yes, how did they make the pressure?
