深轧是一种机械表面处理，可以显著改变金属部件的特征，尽管它已经使用了很长时间，但迄今为止，主要工艺参数之间的相互作用的影响尚未得到彻底理解。为了填补这一空白，这项工作解决了深滚压的表面光洁度和机械性能的影响，从分析和实验的观点。更具体地说，深轧制压力和道次对表面粗糙度，硬度和残余应力诱导AISI 1060钢的影响进行了研究。研究结果表明，深轧后的表面粗糙度与工件的屈服强度密切相关，现有的模型可以很好地预测前者。当采用单一深轧道次时，以及当工作材料的屈服强度增加时，数学和实验硬度值之间实现了更好的一致性。无论所选择的热处理工艺和深轧工艺参数如何，深轧后都会产生残余压应力。最后，提出的模型来预测残余应力提供的结果最接近的实验数据，特别是当退火材料被认为是。
Deep rolling is a mechanical surface treatment that can significantly alter the features of metallic components and despite the fact that it has been used for a long time, to date the influence of the interaction among the principal process parameters has not been thoroughly understood. Aiming to fulfill this gap, this work addresses the effect of deep rolling on surface finish and mechanical properties from the analytical and experimental viewpoints. More specifically, the influence of deep rolling pressure and number of passes on surface roughness, hardness and residual stress induced on AISI 1060 steel is investigated. The findings indicate that the surface roughness after deep rolling is closely related to the yield strength of the work material and the available models can satisfactorily predict the former parameter. Better agreement between the mathematical and experimental hardness values is achieved when a single deep rolling pass is employed, as well as when the yield strength of the work material increases. Compressive residual stress is generally induced after deep rolling, irrespectively of the selected heat treatment and deep rolling parameters. Finally, the model proposed to predict residual stress provides results closest to the experimental data especially when the annealed material is considered.
