Abstract
The mechanical properties of ultrafine lath-shaped low-carbon steel plates were studied. Results indicated that the hardness and tensile strength of the conventional low-carbon steel are HRC 19 and 410 MPa, respectively. With the decreased grain size of the ultrafine lath-shaped steel plates, the hardness and tensile strength of the test samples rapidly increase. Mechanical properties are at their optimum when grain size reaches 90 nm. Furthermore, both the hardness and the tensile strength values reach their maximum, which are HRC 53.5 and 1217 MPa, respectively.
