Acicular ferrite microstructure in micro-alloyed steels, which nucleates around non-metallic inclusions, especially oxide inclusions, has high strength and good toughness and possesses strong grain-refining ability by itself. The ultra-fine grained steel with excellent weldability is likely to be produced by forming in materials a great number of fine and dispersive micro-inclusions which is helpful to induce AF to nucleate around them through oxide metallurgy technology.

Adding transition metals into the TiN films by arc ion plating (1) The hardnesses of theN films are higher that that of the TiN films, proving that the alloy hardening effect is a common phenomenon;(2) The structures of the alloyed films are determined by the added element properties such as covalent radius, electro negativity, free energy and lattice parameters of the MN compound;(3) theN film consists of a mixture of multi phases with high hardness but quite brittle, while the other MN films are composed of single phase with the fcc TiN structure and their hardesses, functions of the added amounts of the elements, manifest always a maximum at a certain M percentage.
