One of the possible causes for disagreement in
compounds identification occurs between metallurgists and crystallographers.
The data in these databases illustrate that the carbides can show many crystalline structures and some data phases are very old referring to compounds with a typical stoichiometry.

Aero engine casing is made of high-temperature alloys and titanium alloys.
Due to difficult cutting properties of high-temperature alloys, the cutting zone has a high temperature.
Due to the high temperature alloys containing a lot of intermetallic compounds, which makes the mechanical properties and heat-resistant quality of the material change great.
If we can build a model of the cooling effect of cutting to lower the temperature of the cutting area, it has a huge role in promoting the development of high-speed cutting super alloys.

In this study, Zn-3Mg alloy was prepared using conventional casting method and followed by homogenization treatment (370oC for 10hr) with the aim to improve the microstructure uniformity.
Due to this limitation, researchers keep investigating other types of potential metallic biomaterials including Mg and Zn based alloys.
Elemental and compound analyses were conducted using energy dispersion x-ray analysis (EDX) and x-ray diffraction (XRD) respectively.
Compound analysis was conducted on the cast alloy using XRD and the results of x-ray diffraction patterns are shown in Fig.3.

The structure and mechanical properties of Ni3Al intermetallic compound were studied in this article.
The aim of this work is to study and compare the structure and the mechanical properties of Ni3Al intermetallic compounds, fabricated by different combinations of mechanical activation of Al and Ni powders, self-propagating high temperature synthesis (SHS) and SPS.
After 3 minutes of mechanical alloying (without SPS and SHS) XRD patterns demonstrated only Ni and Al peaks (Fig. 1b).

Two families of alloys have been studied for this purpose, Cr-Mo-W and Cr-Ta-X alloys (X= Mo, Si, etc.) respectively.
The compositions of the Cr-Ta alloys were chosen regarding the Cr-Ta binary phase diagram, with the aim to re-homogenise the sample by an appropriate thermal treatment and to precipitate the strengthening phase at lower temperature.

Cast alloys have heterogeneous structure and properties, so the welding of the cast designated alloys is still a challenge.
For welding of the cast alloys an increased interest appears for the magnesium [5, 6] and nickel alloys [7].
The overall effect is similar to that registered in the case of the aluminum heat treated alloy, and crack occurrence is connected with the resolidified products: liquation products, precipitated metallic compounds and coarsened constituents.
The aim of it is to complete the information about welding the cast alloys, the best way to understand the peculiarities of the cast alloys behavior and of the main influences that affect the microstructure and, as consequence, the alloy properties into the PMZ.
