The study on TiAl alloy powders with different density by low temperature diffusion synthesis Jun Wang, Huiping Shao *, Zhimeng Guo School of materials science and engineering, University of Science and Technology Beijing, Beijing 100083, China Corresponding author, E-mail: shaohp@ustb.edu.cn Keywords: TiAl alloy powders; intermetallic compounds; diffusion reaction; low temperature; high vacuum Abstract.
This process of forming alloy materials has the advantage that the raw materials are elemental powders or alloy powders, therefore it is easy to fabricate near-net-shaped TiAl alloy products through shaped and sintered.
For example, low density powders for porous materials and high density powders for compacting materials [12].
(3) It can provide an economical method to prepare the starting materials for porous materials.

They noted that the change in friction coefficient with temperature depends on the type of the plastic materials used.
Our literature review reveals that there is no comprehensive study considering the effect of above mentioned parameters on friction measurement of glass materials when they behave as viscoelastic (time-dependent) materials [4, 24].

As-obtained activated carbons were adopted as electrode materials to construct asymmetric and symmetric supercapacitors.
In general, the electrode materials of supercapacitors can be categorized into three types: carbon materials, conducting polymers and metal oxides[3,4]; and the same materials are usually adopted to fabricate the positive and negative electrodes of traditional supercapacitors with symmetric configuration.
The former refers to a supercapacitor involving different materials with different energy storage modes.

Introduction From the mechanical perspective, engineering material which consists of many different componential phases is inhomogeneous material.
So, the more differences of the equivalent stress at the interface of Si particles and Al matrix, the more drop and fracture in the use of the materials.
