The gaseous impurities in the alloys were well controlled with the sum of C, N and O less than 500wppm. For the first time it was found the strong interaction between Cr-Ti-CON, which reduces the mobility of Ti and CON, enhancing high-temperature strength and the aging-hardening property, and keeping the cold-work induced hardening at higher temperature. Aging-hardening could increase the tensile strength of V-4Cr-4Ti by 30% and could be utilized at 00 C for better economical performane of a vanadium structure. Hydrogen release will occur for the alloys tensile loaded at room temperature, which will affect the safety of a vanadium structure due to the resulting dimensional instability. For hydrogen embrittlement, impact toughness and fracture toughness of the alloy showed higher sensitivity than the tensile test elongation,so the toughness should be used as a new standard for the assessment of the embrittlement. Vanadium alloys were easily oxidized in air.

The results show that the addition of cross-linker makes tensile strength of the material greatly increase. After the addition of dialdehyde starch, the tensile strength raises from 7. 2MPa to 13. 2 MPa. However, the strength of the material cross-linked by TDI greatly increases when the additive level is less than 10% while the tensile strength of sample whose additive level is 20% is even worse, which is mainly caused by the inner-flaw after cross-linking.
