The steels with an acicular ferrite microstructure show excellent mechanical properties, such as high tensile strength and toughness. Here, the reasons for good properties of acicular ferrite were discussed with the consideration of its crystal morphology and phase microstructure. The heterogeneous nucleation mechanism and the main factors that influence the nucleation of acicular ferrite in steels were also analyzed. Finally,some prospects was put forward. Source

The infinite chill roller made of the Ni-Cr-Mo cast iron is widely used in the bar rolling mill, because of the advantages such as high hardness and good abrasion resistance. However, the roller can not satisfy the needs of rolling mill for the high alloying and largescale bars. The insert casting process that can improve the core strength of the roller by inserting 45# steel in the infinite chill roller was developed. The results show that the insert casting is feasible and the roller can satisfy the practical rolling needs. Source
