Introduction Metals with high combustion enthalpies are of interest as high energy density materials.
Based on recent research [4] linking phase transformations to macroscopic events during combustion of metal particles, interest in metastable intermetallic materials developed.
A detailed characterization of phase relations and the degree of metastability in metastable Al-Ti alloys is needed to attempt performance optimization of these materials as advanced energetics.
Starting materials were elemental powders of Al (Alfa Aesar, 99.8 %, -40+325 mesh) and Ti (Alfa Aesar, 99 %, -325 mesh).

This project learns from the lesson to make adequate preparation, particularly standby materials in place.
(2) Make strict control of raw materials.
Start construction procedures from raw materials of commercial concrete, mix proportion, water-cement ratio, workability, slump, transport, pouring, vibration, curing to temperature measurement, etc, by strictly following construction specifications to ensure concrete construction quality.

Furthermore, TBC coatings are more susceptible to erosion due to their porous structure than full dense ceramic materials.
Furthermore, TBC coatings are more sensitive to erosion than full ceramic materials because they have a porous structure [10].
Furthermore, the impacts on coating made of porous materials (eg [19]), two-phase polycrystalline materials (eg [20-25]) as the structure of the functionally graded material (eg [26, 27]) or layered structures [28-34] will be considered.

One of the still open research front end is the enhancement of the material formability, especially for some alloys.
As the temperature increase was localized near the forming tool, i.e. in the area of the material that is being formed in a given moment, no detrimental effect related to keeping the material at elevated temperatures for long times is produced.
It should be observed that no former accumulated plastic strain and/or material strain hardening have been taken into account.
The numerical model was utilized to explain the different behavior of the material at the varying of the process conditions.
