The effect of interlamellar spacing on strength of pearlite in annealed eutectoid and hypoeutectoid plain carbon steels

The effect of electropulsing on the interlamellar spacing and mechanical properties of a hot-rolled 0.14% carbon steel

“…However, the effect of electropulsing on the values of hardness and yield strength lessens after 100 electric current pulses. It has been frequently reported in the literature [16,17,18,19,21,22,23] that hardness and yield stress follow a Hall-Petch type relationship as follows:…”

Mechanical Properties of α+κ Two-phase Lamellar Structure in Fe-Mn-Al-C Alloy

“…Pearlite steels have been reported that their strength follows a HallPetch like relationship with the mean inter-lamellar spacing between and cementite phases. [13][14][15][16][17][18][19][20] It is expected that the strength of þ two-phase alloy also follows a Hall-Petch like relationship. The aim of the present investigation is to examine the correlation of the mean inter-lamellar spacing on hardness or yield stress of þ two-phase lamellar structure.…”

Advanced Possibilities of Fast Quality Check in Wire Production Processes by Means of Fast Microstructure Analysis

“…Therefore it can be assumed that the finer the pearlite structure the higher will be the microstrains measured by FMA and a good-quality proportional correlation of ε 2 100 and lamellar density, which was calculated as the reciprocal mean apparent interlamellar distance ILD determined from SEM pictures could be observed. As widely known, e. g. [7], the pearlite lamellar density also correlates with the strength of fully pealitic steels. This relationship was applied to the C80 wire samples examined during this study and a reliable proportional correlation was found to be valid between lamellar density, tensile (and also yield) strength and the mean squared microstrain determined by FMA.…”
