Introduction One-dimensional nanostructured materials with a variety of forms, such as nanotubes, nanowires, nanobelts, and nanofibers, are of great interest due to their unique properties and intriguing applications in many fields.
Among various methods to prepare these materials, electrospinning is currently one of the most versatile and promising processes for producing continuous nanofibers for both fundamental and application-oriented research mainly due to its capability and feasibility in generating large quantities of nanofibers with well-defined surface topologies at relatively low cost [1-3].

Crystal growth KBBF material used in this study was obtained by a chemical reaction between KBF4 and BeO.
The chemically pure materials of KBF4 and BeO were purchased from Shanghai Chem.
The material was further purified by the vacuum distillation for several times before starting the crystal growth experiments.

High current flows between gripping jaw and anvil; the material between anvil and jaw is heated and enters the plastic condition.
Under the action of the pressure of the upsetting cylinder the heated material is upset.
Contrarily, if the forming temperature too low or the forming velocity is too high, the material folds.
If neck length is high, material flow will not happen in the forging process due to spherical bulb shape.

In recent years, there are many researches [2-4] concetrated on the materials used in sluury pumps and their wear behaviors.
Table 1 listed the chemical composiotion of the material (KMTBCr26 alloy) used to produce the volute.From Table 1, it can be seen that it is a kind of high chromium cast iron.
Fig.1 the 3 d solid modeling of the volute Table 1 the chemical composiotion of the material used (wt%) C Cr Si Mn Ni Mo P S Fe 2.6-3.0 26-30 0.6-1.0 0.8-1.2 0.5-1.0 0.0-0.8 ≤0.06 ≤0.06 Bal.
Due to the large phase transformation stress of the material and internal stress caused by parting surface joint and the uneven cooling of the casting, cracks are easily formed during the production of the part.

The following conclusions were obtained from the analysis results:(1)the rationality and effectiveness of the presented nonlinear multi-node sliding cable element was verified for both sliding and non-sliding situations; (2) with the sliding of the latitudinal cables, uniform axial force distribution can be achieved for the tensegric system of the Suspen-Dome, which is helpful for improving the material efficiency of the cables and preventing the cables from sagging under asymmetric loads;(3) whether the latitudinal cables can slide or not has little effect on static behaviour and nonlinear stability of the single-layer lattice dome even under asymmetric loads.
