The creation of duraluminium
Mark Miodownik describes how Alfred Wilm's experimentation with alloys came up with duralumin in 1903. This alloy is a mixture of aluminium, manganese, copper and magnesium. A key part to this story is how Wilm discovered age hardening (alloys becoming stronger over time) by accident. Mark Miodownik describes the crystal lattice structure of alloys.
