摘要：

Specially prepared low-carbon steels with pearlite fractions varying from 0.19 to 100% have been used to study the independent effect of carbon content and microstructure on the structure-sensitive magnetic properties of low-carbon pearlitic steels. Increased magnetic hardness with carbon content has been observed in the initial magnetisation and hysteresis curves. The changes in the magnetisation processes were investigated by studying the Barkhausen noise emissions and observing the domain wall motion directly using Lorentz electron microscopy. The increase in pearlite content significantly enhanced the effectiveness of cementite lamellae at pinning domain walls.
