“…As sizes of parts become smaller, material grain sizes have an effect on the formed dimensions [1][2][3], because of increased ratio of a grain to the surface area. Fine-grained steel had been required for high-precision micro-forming [4][5][6]. Control technologies of material grain size had been developed for austenitic stainless steel, such as JIS-SUS304 [7][8][9][10][11].…”

Over the last decade, development of fine-grained materials and investigation into the effect of different grain sizes on metal forming at the micro-scale have been seen worldwide. There were several technical reports and scientific papers dealing with the quality improvements with use of the ultra-fine grained steel due to the different grain deformations. However, there were few studies concerning effect of the grain size on the sheared surface in micropiercing. In this study, we investigated stability of the sheared surface length of the cross section in micropierced holes. The inner diameter of the holes and maximum piercing forces were measured in order to evaluate the effect of the grain size in the micropiercing process. As reducing the material grain size, ratio of the fractured surface and maximum piercing force increased with tendency to tensile strength. However, the ratio of the burnished surface to the fractured surface as well as inner diameter of the pierced holes varied, depending on the grain size of the material. As a result, a suitable grain size should be considered for a micropiercing process.

Abstracts In this work laminar steel materials of W1-7 + AISI 304, W1-7 + AISI 430, 1008 + AISI 304 and 1008 + AISI 430 model compositions were studied. The γ→α transformation temperature range bias and influence of such bias dynamics on the laminar structure stability was studied by the differential scanning calorimetry method. The study results have shown that only in the laminar steel material of W1-7 + AISI 304 model composition the γ→α transformation temperature range bias to the low temperature region and the expansion of austenite field occurred, thus ensuring retention of the laminar structure in the process of material synthesis. Also, the nature of γ→α transformation was analyzed for all four compositions which showed that the observed γ→α transformation for each model composition of laminar steel materials was direct.
