Serbian.
Why we are doing post heating in alloy steel welding?
What are the compositions of brass, how can this metal be heat-treated, what is the melting point of this metal?
How we describe strain aging based on dislocation theory?
How does and why the recrystallization temperature of the metals affects on alloying?
What is proeutectoid ferrite and cementite?
What is the metallurgy use? What is the casting and forging?
Which is the only liquid in which gold is dissolved?
How much gold concentration should be in the organic phase (DBC) before reduction by oxalic acid solution? Is it effective on purity of gold in reduction step? What is the ratio of DBC to oxalic acid solution in this step?
How is solution annealing carried out? What type of furnace is required? Does one need to be heat in a Salt Bath?
Will aluminum alloy like 380 or 356 settle? Meaning while in "Liquid form" above melting point will the heavier elements like copper, Fe, Silicon, zinc etc. settle to the bottom of the liquid/molten aluminum after a period.
