Hot hardness
Okay kiddo, imagine that you have two different kinds of candy bars. One of them is really soft and chewy, and the other one is really hard and crunchy. Now, let's pretend that you wanted to use each of these candy bars to smash some rocks. Which one do you think would be better for the job?
Well, the hard and crunchy candy bar would probably work a lot better, right? That's kind of how hot hardness works. It's all about how well a material can resist getting bent or broken when it gets really, really hot.
When things get hot, they can expand and change shape. That can put a lot of stress on a material, and if it's not strong enough, it might start to break or wear down. But if a material is "hot hard," that means it's really good at taking that heat and not changing shape or getting damaged.
So, let's say that we have some metal. If we heat it up a lot, it might start to get softer and bendy. But if we have a type of metal that is hot hard, it will stay strong even when it's really hot. That means we can use it for things like making tools that have to withstand high temperatures, like cutting through metal or grinding rocks.
Basically, hot hardness is all about how tough a material is when it gets super hot. And just like how the hard candy bar can smash rocks better than the soft one, materials with good hot hardness can last longer and work better in really tough conditions.
