The production of titanium is very expensive, so it is interesting to research technologiesthat require lower costs, such as the HDH hydrogenation-dehydrogenation processtechnology, which is used for cheaper powder production from the waste material oftitanium alloys.This paper presents the hydrogenation procedure of a recycled piece of the Ti6Al7N...

Ratio of ultimate tensile strength and yield stress shows lower values in cold drawn wire than in hot rolled state. The results of research addressing the effect of variations in chemical composition of continuous casted billets on mechanical properties of cold-formed wire used in production of steel mesh are presented. In the c...

The impact of chemical corrosion on the durability of tundish working lining based on slurry mix is discussed in this work. The results of chemical and mineralogical analysis in the sample of tundish working layer after lining lifetime are presented. Infiltration of slag effected in a reduced thermal shock resistance resulting in thermal stress on ...
