Bending distortion analysis of a steel shaft manufacturing chain from cold drawing to grinding
Dias, Vinicius Waechter; Rocha, Alexandre da Silva; Zottis, Juliana; Dong, Juan; Epp, Jérémy; Zoch, Hans-Werner (2017) [Artículo de periódico]Shafts are usually manufactured from bars that are cold drawn, cut machined, induction hardened, straightened, and finally ground. The main distortion is characterized by bending that appears after induction hardening and ... -
Effect of compressive deformations on the final microstructure of a low carbon high silicon bainitic steel thermomechanically processed
Hatwig, Rodrigo Afonso; Dong, Juan; Epp, Jérémy; Rocha, Alexandre da Silva (2021) [Artículo de periódico]Due to a combination of advantages, high-performance steel components, especially for automotive manufacturing applications, are generally forged parts. In the forging industry, bainitic steels are being increasingly used, ... -
Investigation of the influence factors on distortion in induction-hardened steel shafts manufactured from cold-drawn rod
Dong, Juan; Epp, Jérémy; Rocha, Alexandre da Silva; Nunes, Rafael Menezes; Zoch, Hans-Werner (2016) [Artículo de periódico]In this study, the distortion of steel shafts was investigated before and after induction hardening. Several essential influencing factors in the manufacturing process chain regarding cold drawing, cutting method, notches ... -
Propriedades do aço AISI 4140 nitretado a gás
Diehl, Igor Luís; Dong, Juan; Rocha, Alexandre da Silva (2017) [Artículo de periódico]Nitretação está entre os tratamentos superficiais mais efetivos. Os principais benefícios da nitretação aos aços são o aumento da dureza, resistência ao desgaste, resistência à fadiga e resistência à corrosão. Com isso, ... -
Revealing the dynamic transformation of austenite to bainite during uniaxial warm compression through in-situ synchrotron X-ray diffraction
Bevilaqua, William Lemos; Epp, Jérémy; Meyer, Heiner; Dong, Juan; Roelofs, Hans; Rocha, Alexandre da Silva; Reguly, Afonso (2021) [Artículo de periódico]In this work, the microstructural evolution during the dynamic transformation of austenite to bainite was directly observed by in-situ high energy synchrotron X-ray diffraction measurements during warm uniaxial compression ...
