The addition of V element can be stabilized in Al12(Fe, V)3Si Si phase; and the addition of Si can inhibit the second-phase dispersion phase coarsening and decomposition, increase the high temperature stability of materials; Fe/V ratio affects the coarsening rate of second-phase particles, thus affecting the thermal stability of materials.
Starting from the influence of alloy composition on the performance of the organization and the melt, by controlling the rapid solidification process parameters, can significantly improve the performance and quality of metal materials, the organization, has opened up a new and effective way for the performance potential of mining materials, has broad application prospects[3, 4].

Introduction Wire-EDMing process can cut the electrical conductive materials without the presence of significant mechanical stresses in the workpiece due to the noncontact of electrode with work material.
Using the high open voltage and rough cutting mode, more heat energy created can be likely conducted into not only the workpiece but also the wire electrode, hence removing more work and electrode materials accordingly.

We present numerical simulation of air entrapment in composite materials manufactured by the resin transfer molding (RTM) process.
The prediction of air void formation has been an important topic because air voids in composite materials deteriorate the mechanical properties of the part.
