The relationship between recrystallization temperature, grain size, and the Charpy impact properties of V-Cr-Ti alloys
Technical Report

OSTI ID:47751
It is shown that the blunt notch Charpy impact properties of a V-5Cr-5Ti alloy are extremely sensitive to the grain size distribution developed during the final annealing treatment. Ductile behavior down to liquid nitrogen temperatures can be induced, for example, by a treatment at 950{degrees}C, rather than annealing at 1125{degrees}C. It is proposed that the resistance to irradiation-induced shift in DBTT reported by Argonne National Laboratory (ANL) researchers for the V-4Cr-4Ti alloy is related primarily to the exceptionally fine-grained microstructure developed during the low temperature processing route adopted for this alloy.
