interstitial-free steel

interstitial-free steel

[‚int·ər′stish·əl ′frē ′stēl]
(metallurgy)
An aluminum-killed steel with an extra-low carbon content, nominally 0.005%, in which the residual carbon is combined with niobium (columbium), titanium, or some similar element with a strong affinity for carbon.

This paper describes results of a study of hydrogen charging during the hot dip galvanization process of two advanced high strength steels, dual phase grades DP600 and DP980 in comparison with interstitial-free steel used as a reference.
The project began when ArcelorMittal Dofasco s leadership challenged the steelmaking production unit to increase throughput of ultra-low carbon interstitial-free steel and advanced high-strength steels to meet future market demand.
Among specific topics are measuring strain and lattice rotation in the particle deformation zone, microstructure and texture evolutions in a short-time-annealed interstitial-free steel, the recrystallization of cold-rolled zirconium single crystals, the influence of finishing rolling variables on austenite recrystallization and grain growth, and the orientation of island and small grains in grain oriented electrical steels.
Among specific topics are the cyclic stability and fatigue performance of ultrafine-grained interstitial-free steel under mean stress, the cyclic depth-sensing indentation of gold wire, direct comparisons of fatigue behavior in bulk-metallic glasses and crystalline alloys, and a dissipated energy approach to fatigue crack growth in ductile solids and layered materials.
