Abstract

In this experimental study, the strip formed specimens made from aluminum alloy 1030, pure Cu, CuSn7, CuZn30 and low carbon steel 6114 were cold worked to different ratios. To be able to determine the microhardness values of the materials, the microhardness tests were applied. Grain sizes of the materials were determined by the Heyn method using metal microscope.
The hardness of materials H, is dependent on the grain diameter, d, in a similar way as in the flow stress in the Hall-Petch relation: H=H0+KHd-1/2 where H0 and KH are constants. The microhardness of the materials is found to vary with the grain size according to the Hall-Petch equation with reasonable accuracy.
