摘要：

This paper presents the results of research regarding cracking causes of a driving wheel made from microalloyed boron forged steel. Researches include analysis of two samples: first from a rolled bar (forged material) and second from cracked surface. The following methods and techniques for investigation were used: -Visual examination; -Scanning Electron Microscopy (SEM) examination for cracked surface of material and its adjacent area; -Energy Dispersive Spectra (EDS) examination for micro-composition characterization.
