The Mg element blocks the distributed glide of dislocations and thus inhibits the formation of cell structures due to the large atom radius,producing high aberrance energy and internal friction in Al matri.

The addition of 5 mg·L -1 of CTAB eliminates the cell structure of traditional Ni-P coatings and improves the uniformity of the coatings.

In this paper,the mechanism of formation of zonal structures in low-carbon alloy steel and three methods for removing them are introduced.

The results revealed that the non homogeneous distribution of the carbide caused the “zonal structure” appeared in the joint of drill rod which is hardened and hightemperature tempered.

Effect of Banded Structure in Low Carbon High Sulphur Free Cutting Steel on Crack Formation of Cold Drawn Products;

Formation and elimination of banded structure of 20CrNi2Mo steel;

The effect of finishing rolling temperature on banded structure of 16Mn steel plate;

Effects of band structure on SSCC and CO 2 corrosion;

This article focused on the effect of microstructure,especially the band structure to HIC-resistance of pipeline in H2S containing solutions with special attentions on the initiation and expansion of cracks.

The tested results show that, the band structure of G20CrMi2MoA steel is eliminated by current impulse method in short time, and the grain size is refined at the same time.

For isothermal treated plates at 600℃ for 20min after rolling process, the banding microstructure of theplates containing 0.

Experimentally, both the evolutions of interfacial morphology, and the typically solidified features, such as competitive growth of the two phases, coupled growth and banding microstructure were observed, which provide the clue for the further control of the mi.
