WebSep 4, 2024 · Some rotors are bent permanently due to high operating temperatures, repeated transition periods, and so on. Rotors with large deformations often require straightening processes. The goal of this study is to develop a method to determine the optimal locations and strengths of hammer peening for straightening gas turbine rotors. … WebAug 7, 2024 · As it was explained to me, the steel shrinks more when it cools than it expands when you heat it. By selectively heating the areas that need to shrink, you can change the shape of the fabricated piece. Whether it would be enough to get your piece back to the shape you want, I don't know, but I thought it would be worth looking into. http://steelstraightening.com/ reach research
