    Strength
In summary, the conversation discusses the concept of hardness and brittleness in materials. The speaker is confused about how a substance can be both hard and brittle, and asks for clarification with some numerical examples. The response explains that hardness refers to the resistance to compression and flexibility, while brittleness refers to the ability to absorb vibration or impact. Therefore, a substance can be hard but brittle if it is difficult to compress but easily breaks under force.

I am coming across definitions which says certain substances (like martensite) are hard but brittle. I can't understand the meaning.
Brittle substances have yield strength closer to breaking strength. If something breaks/fails easily then how can it be hard..?
Pls help me out with some numbers...

It can be hard to compress the material - you need a large force for a tiny change in its shape/volume/...

the harder they are the less flex they have and they will break easier to a point. its like mounting something up completely solid. its harder but more likely to break things because it cannot absorb vibration or impact as good. it just takes the force. so a certain force will be lower on something with more flexibility. I think I kind of rambled. but it makes sense to me
