1. Utilization of waste materials for extraction of strategic metals : a biogeochemical approach
Abstract : Worldwide the modern society produces vast amounts of waste materials containing strategic and valuable metals. Some of them are of substantial economic or environmental significance if controlled recovery of metals can be performed or if uncontrolled release to the environment occurs. READ MORE

2. A Study on Vanadium Extraction from Fe-V-P Melts Derived from Primary and Secondary Sources
Abstract : Vanadium extraction methods were developed for iron-vanadium-phosphorus (Fe-V-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. READ MORE

3. Secondary hardening in some low-chromium hot-work tool steels
Abstract : Low-chromium hot-work tool steels combine good heat conductivity with excellent tempering resistance. This property combination has made these steels ideal for die casting and extrusion. READ MORE

5. Investigation of vanadium-containing oxide systems : CALPHAD and experiments
Abstract : Fundamental studies on thermodynamic properties of vanadium-containing oxides systems are essential to understand practical vanadium metallurgical process. The CALPHAD technique is here applied to the thermodynamic modelling of the V-O, Ca-V-O and Ti-V-O systems. The compound energy formalism is used for all the solution phases. READ MORE
