; precipitation rate; complex forming rate 1 Introduction In non ferrous metallurgy, hydroxide precipitate method is commonly used to recover valuable metals and purify the leaching solution usually [1-7... forming hydroxide where precipitation and complex are formed together. The effects of some factors on formation of precipitation and complex were investigated, and the corresponding precipitation rates......
by this finite element method. The rheological forming characteristics were well realized and the forming parameters were determined. The results and analysis show that with decreasing strain rate... compared with that produced by traditional method. Key words: TC11 titanium alloy; vane disk; hot rheological forming; numerical simulation; stain rate 1 Introduction Metal rheological forming......
