- The relationship between fracture toughness and notch toughness, tensile ductilities in lath martensite steel has been investigated.
- The tensile strength,yield strength and notch toughness of Q420 angle steel produced by V-N interalloying method were improved evidently and integration properties were better.
- I am well aware that this is a tough job.
- The monitor is really a notch above us.
- He'll never pay up unless you get tough with him.
- He cut a notch in the stick with a sharp knife.
