Impact properties of microalloyed steels
Impact properites of two grades of microalloyed steels (Re>MPa) work hardened by static and dynamic inuaxial tension are presented. Properties are analysed by impact testing at very high impact loading rate (v=785 m/s) and by fatigue testing at ultrasonic, high frequency (20 kHz). Results indicate that the test mechanical properties of work hardened steel are not influenced by prime work hardening strain rate change sin the range from 0.001 to 100 s/. At high speed impact the steel showed good plastic properties and high resistance to perforation for the given strength. In fatigue experiment the tested steel showed high resistance to fracture and were not significantly sensitive to the increase of loading frequency in the decreasing part of the Wohler Curve. The tested microalloyed steel application is recommended for structures stressed by booth static and dynamic loading.
