Influence of Steel Grain Size on Residual Stress in Grinding Processing

Abstract: Abstract. The fine-grained rolling steels NFG600 and the conventional usual rolling steels SM490 were processed by sand paper polishing and mechanical grinding to compare the residual stress generated after processing. The average grain size of NFG600 and SM490 is 3 µm and 15µm respectively. Therefore improvement of mechanical properties for such fine-grained steels is expected, it is important to understand the residual stress state of new fine-grained materials with processing. In this study, multi axial str… Show more

“…In other words, grain refinement would result in lower tendency for surface tensile RS11 (or higher surface compressive RS11). It is worth mentioning that, the current results are in agreement with the experimental results of Gotoh et al [1], when they grinded two types of steel; a fine-grained rolling steel "NFG600" and a conventional rolling steel "SM490".…”

“…Larger grain size (lower yield strength) resulted in higher surface tensile RS, which was attributed to higher compressive plastic deformation and higher workpiece temperatures. The current results also agree with the experimental findings of Gotoh et al [1].…”
