Simulation studies on metastable phase equilibria in the aqueous ternary systems (NaCl-MgCl

Tianlong DENG, Baojun ZHANG, Dongchan LI, Yafei GUO

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2,   Pages 172-175 doi: 10.1007/s11705-009-0048-1

Abstract: The solubilities and densities of the aqueous metastable ternary systems (NaCl-MgCl -H O) and (KCl-MgCl -H O) at 308.15 K were determined by the isothermal evaporation method. On the basis of the experimental results, the phase diagrams for those systems were plotted. It was found that the former system belongs to the hydrate-I type with one invariant point of (NaCl+ MgCl ?6H O), two univariant curves, and two crystallization regions corresponding to halite (NaCl) and bischofite (MgCl ·6H O); and the latter system belongs to the type of incongruent-double salts with two invariant points of (KCl+ KCl·MgCl ·6H O) and (MgCl ·6H O+ KCl·MgCl ·6H O), three univariant curves, and three crystallization regions corresponding to potassium chloride (KCl), carnallite (KCl·MgCl ·6H O) and bischofite (MgCl ·6H O). No solid solutions were found in both systems.

Robust optimization of the billet for isothermal local loading transitional region of a Ti-alloy rib-web component

Ke WEI, Xiaoguang FAN, Mei ZHAN, Miao MENG

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 3,   Pages 376-384 doi: 10.1007/s11465-018-0500-3

Abstract:

Billet optimization can greatly improve the forming quality of the transitional region in the isothermal local loading forming (ILLF) of large-scale Ti-alloy rib-web components. However, the final quality of the transitional region may be deteriorated by uncontrollable factors, such as the manufacturing tolerance of the preforming billet, fluctuation of the stroke length, and friction factor. Thus, a dual-response surface method (RSM)-based robust optimization of the billet was proposed to address the uncontrollable factors in transitional region of the ILLF. Given that the die underfilling and folding defect are two key factors that influence the forming quality of the transitional region, minimizing the mean and standard deviation of the die underfilling rate and avoiding folding defect were defined as the objective function and constraint condition in robust optimization. Then, the cross array design was constructed, a dual-RSM model was established for the mean and standard deviation of the die underfilling rate by considering the size parameters of the billet and uncontrollable factors. Subsequently, an optimum solution was derived to achieve the robust optimization of the billet. A case study on robust optimization was conducted. Good results were attained for improving the die filling and avoiding folding defect, suggesting that the robust optimization of the billet in the transitional region of the ILLF was efficient and reliable.
