The study looked at how different rolling temperatures affect the strength and structure of IMI550 alloy bars. They rolled the bars at three temperatures and found that each temperature resulted in a different type of microstructure. Despite the differences in structure, the strength of the bars at room temperature and high temperature did not vary much. The bars with a basketweave structure had the best creep properties, while the bars with a duplex structure came in second. The bars with an equiaxed structure had the poorest creep properties.
