dc.description.abstract | The work presents the surface changes in microstructure and properties by
quenching the 51CrV4 steel from liquid and solid phase, using a CO2 continue laser
wave with 900W power. In order to determine the hardening conditions, processing
parameters on the geometry of the hardened layer and surface hardness were
analyzed. Microhardness profile of heat affected zone was traced and correlated
with structural changes. The effect of subsequent tempering was investigated. | ro_RO |
