摘要：

The present paper is concerned with the method of deformation networks in the range of stampings drawing from sheet-metal. The influence of circular grids, made by embossing with the use of special apparatus for grid marking, upon sheet-metal is described. The sizes of impressions and the influence of the embossed circular grids upon the sheet-metal properties were determined for two cases of adjustment of apparatus for making impressions-on impression depth of 0.06 and 0.05 mm. In both cases of apparatus adjustment from measured values of HV 0.01 in the direction normal to the sheet-metal surface in the place under the impression and in the surroundings, it was found that in the embossing of the impression on the sheet-metal a substantial influence upon the ferrite grain microhardness does not occur deeper under the sheet-metal surface.
