Hardness can be rephrased as surface strength, while toughness can be described as strength against impact.
What is lost when something becomes hard? That is toughness. Toughness is like the ductility that a material possesses. When hardness increases, this ductility is compromised. What happens when toughness is compromised? Let’s take diamond, the hardest mineral in the world, as an example. While diamonds are thought to be extremely hard, this is only effective against wear and scratches; they can easily break when subjected to impact, such as from a hammer. This indicates that while diamonds have very high surface hardness, their internal toughness is very low. *For more details, you can view the related links.
