Impact properties of microalloyed steels
Metalurgija, 2000 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).

Compressive creep behavior of alloys based on B2 FeAl [PDF]
Alloys based on FeAl are attractive alternate materials for environmental resistance at intermediate temperatures. Addition of small amounts of Nb, Hf, Ta, Mo, Zr, and B were shown to improve the compressive creep of this alloy at 1100 K.
