The researchers studied how abnormal microstructures form in hot rolled plates of titanium alloys. They experimented with different alloy compositions and rolling conditions to understand this process. They found that the abnormal microstructure is elongated and forms during rolling from existing abnormalities in the material. The temperature during rolling affects the severity of the abnormal structure. This structure is harder and contains more specific elements than the surrounding material. Plates with this abnormal structure have reduced elongation and show significant differences in tensile properties.
