Introduction Bismuth Sodium Titanate (BNT) is the base compound for a family of lead-free piezoelectric materials [1-3], because of its extraordinary large strain induced by the electric field [4].
As starting materials for the synthesis Bi2O3 (99.9 %, MCP-HEK GmbH), Na2CO3 (99.99%, Merck), TiO2 (99.8 %, Tronox), ZrO2 (99%, MEL Chemicals), GeO2 (99.998, Aldrich) and SnO2 (99.9, Aldrich) were used.
All starting materials were dried at 260 °C for 48 h to avoid weighing errors caused by adsorption of humidity.
After the drying, the materials were cooled and stored in a desiccator over silica gel.

Study on Effect of Extrusion Velocity on Composites Liquid-solid Extrusion Process using 3D Thermo-mechanical Simulation Zhenjun Wang1, a, Lehua Qi1, b and Jiming Zhou1, c 1 The Key Laboratory of Contemporary Design and Integrated Manufacturing Technology, Education Ministry of China, School of Mechatronic Engineering, Northwestern Polytechnical University, Xi'an, 710072, P.R.China a wangzhj@mail.nwpu.edu.cn (corresponding author), bqilehua@nwpu.edu.cn, c zhoujiming@nwpu.edu.cn Keywords: extrusion velocity; composites; liquid-solid extrusion; 3D thermo-mechanical FEM.
Furthermore, it was assumed that the heat caused by the friction work flow into the tool and material averagely.
It is well known that the product forming quality lies on the thermo-mechanical state of the material during the forming process.
The results of flowage show that the flow velocity of the inner and outer material was uneven due to the friction.
On the contrary, the forming temperature is relative low and the fracture strength is high enough to avoid material damage in the non-constant-velocity extrusion.

Sectors such as housing, aerospace and automotive are rapidly growing in developing countries because of the increased demand due to the increasing population, which is one of the driving forces for the supply need and growth of light-weight high-strength materials like Al [2].
For the grain refiner master alloy to act as an effective dopant, the physical nature (shape, size morphology or number density) of the pre-existing phases in the master alloy play a key role in the microstructural development during casting [5].
