Webb19 juli 2024 · Bronze became such a useful product to humans, that an entire period in early civilization became best known as the Bronze Age. Bronze was compact and easy to transport, making it a great commodity to trade. From 1500BC there was another great development in metallurgy, the discovery of iron. WebbThe process is called nucleation, and it involves the formation of a new phase within the pre-existing liquid phase. When such a metal particle has solidified, a new interface is created between the particle and the liquid. This new interface has a positive energy, i.e., energy has to be supplied during solidification to create this interface.
