vvanadium, and titanium, has an extremely high potential value. VTM resources in the PanXi regions of China are estimated at up to 10 Gt (billion tons), and account for 93% and 63% of the country's titanium and vanadium resources respectively. The exploitation of VVTMs has thus received much attention (Barksdale, 1966; Chen et al., 2011).

Alloy steel - Wikipedia

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties.Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.
