So, are you looking to make something out of metal? If so, then you will want to know why forged metal is brittle
The answer is that the metals used in forging have a tendency to crack when they are subjected to stress. This means that, for instance, a piece of metal that has been forged and then bent into shape is likely to break under pressure
The reason for this is simple: the forces involved in bending a piece of metal tend to cause cracks in its surface.
