Microstructural examinations show that the cold rolling process increases the extent of centerline segregation of second-phase particles. The increase in rolling reduction results in a decrease of grain size and a more random distribution of crystallite orientations.Author: Hanliang Zhu, Hanliang Zhu, A.K. Ghosh, K.

What is the microstructure change from annealing?The microstructure change from the annealing process is shown in slide 15 for the 60% CW condition.

What is the microstructure of brass?

The as-received brass was initially cold rolled from a casting into a sheet then annealed. This is why the initial microstructure shows metal grains that are somewhat elongated in one direction (slide 8). Each grain is a single crystal area differentiated from its neighbors by degrees of rotation and displacement.See all results for this questionWhat are the effects of rolling grains?Rolling causes the grains to elongate and introduces defects in the grains called "dislocations" which make it more difficult for the atoms to slide over one another during deformation, thus increasing strength and hardness.See all results for this questionTexture and microstructure evolution during different effect of rolling methods on microstructureThe result showed the rolling method had a minor influence on the rolling microstructure but significant on the rolling texture. Compared to the cold-rolled sheet, the warm-rolled steel showed strong -fiber and -fiber texture at the surface but weak -fiber and -fiber texture in the center layer.
