fracture toughness

fracture toughness

(OP)
does fracture toughness value increases with hardness value

RE: fracture toughness

Usually those two properties are inversely proportional. An increase in hardness will decrease toughness, but this is not universal.

RE: fracture toughness

In many metals the fracture toughness increases as the strength (and hardness) increases, until you get to a tipping point where there is not enough remaining ductility to blunt crack propagation, then toughness drops with increasing strength and hardness.
