Experimental procedure of vanadium hydride

Vanadium, V–5Cr, and V–5Ti alloys were prepared from 99.9% pure vanadium by arc melting in an argon atmosphere. The nuggets were cold-rolled and punched into tensile specimens for in situ straining experiment with a gauge size of 2×7 mm2 and 0.1 mm in thickness. The samples were evacuated in a quartz tube and annealed in a vacuum at 1000 °C for one h. Hydrogen was doped into the samples in a high-pressure oven at 450 °C with 0.5 and 0.8 MPa hydrogen pressures. The first visible evidence of the e
