1, Equiaxial microstructure evolved into fibrous structure at large strain.

2, The fine equiaxial microstructure can obtain better mechanical properties.

3, Equiaxial prestrain will obviously decrease the forming limit on positive strain ratio zone, while it slightly improves the forming limit on negative strain ratio zone.

4, Microstructure of spot-welded joints are mainly composed of equiaxial grains.

5, Based on the cellular automaton (CA) made up of regular hexagon cells, the nearest neighbor type and periodic boundary condition, equiaxial microstructure as parent phase was obtained.

6, Furthermore, both the effect of martensite lath boundaries on the nucleation of dynamic recrystallization, and the mechanism of nucleation and growth of equiaxial nanometer grains were revealed.

7, It is found that after(60%)cold deformation and recrystallization annealing, the UT2 with fine,(http:///equiaxial.html) uniform and equiaxial grains is the best.

8, The fracture toughness of lamellar microstructure is higher than that of equiaxial microstructure when deformed above the phase transition.

9, Segregated solutes and inclusions are distributed at the transition boundary of the column crystal and the equiaxial crystal.

10, The specimens with Widmanstatten structure have higher impact strength and lower ductile-brittle transition temperature than those with equiaxial granular ferrite structure.

11, Moreover, the stronger the pulsed magnetic filed, t he much more refiner and equiaxial effects appears. This novel technique can be used in varies of metal materials and spread in industries.
