But magnesium alloy has a hexagonal close-packed crystal structure with limited number of operative slip systems at room temperature, so magnesium alloys are normally low formability near the room temperature, and limits the expansion of magnesium alloy applications.

但是由于镁合金是密排六方结构，可开动的滑移系比面心立方和体心立方金属的少，使得镁合金的室温塑性较低，降低了成形能力，限制了变形镁合金的推广应用。

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.
