- ‘When these steels are nitrided the aluminum forms AlN particles, which strain the ferrite lattice and create strengthening dislocations.’
- ‘A roof-area cross-member is nitrided (bonding titanium and nitrogen to the parent steel after stamping) to raise its tensile strength to 145,000 lbs/sq.-in.’
- ‘Nitrogen may be introduced into the surface of the steel by nitriding.’
