Most popular composites in use to date in the metal/mechanical domain are based on Al and Al alloys as matrix and SiC or Al2O3 particles as reinforcing elements.
It was detected the formation of circa 8% liquid already at temperatures around 475°C, which is probably due to the melting of intermetallic compounds, such as M (Al3Mg2), T (AlCuMgZn) and S (Al2CuMg) phases.

Alloy development of advanced ferritic steels has shown that the addition of vanadium, niobium and nitrogen can increase creep strength and chromium can provide increased oxidation resistance at higher temperatures.
The main aim was study the influence of the conditions of different tempering temperature and holding time on microstructure, substructure and mechanical properties.
These particles were identified by the selection electron diffraction analysis, as niobium carbides alloyed with boron with possible vanadium atom substitution in the crystallographic cubic NbC centered lattice.
To achieve sufficient strengthening, creep resistant steels usually contain several types of carbonitrides and intermetallic compounds in the matrix and at grain boundaries: carbonitrides including M23C6, M6C, M7C3, MX and M2X, where M denotes a metallic element, and X is carbon and/or nitrogen atoms; and intermetallic compounds such as the Fe2(Mo,W) Laves phase.

By utilizing powder metallurgy (PM) one could benefit from available industrialized approaches for composite production and alloying routes.
Summarizing, the aim of both the chemical vapor infiltrated (CVI) Wf/W and the PM Wf/W development is a composite material with superior properties.

Since precipitation hardening depends on the size and distribution of the precipitates, in general
associated with cooling rate and temperature of hot rolling, the aim of the present work is to
optimize these variables from the point of view to perform the highest possible yield stress.

Successive alloying with refractory metals is performed to the Cu-NiYSZ anode material aiming to free Cu at the precipitated state due to Cu low solubility in the metals.
Accordingly to X-ray analysis (Fig. 7), some compounds were formed after sintering of MA powder pellets submitted to high energy transfer conditions, as a result of C contamination from the container: ZrC and CuZrO3.
Ni peaks are further shifted due to refractory metals alloying while Cu peaks are not preserved.

Currently, structural ceramics or intermetallic compounds are using as heat-resistant and wear-resistant materials.
At this angle of inclination, the laser beam is focused at the initial point and defocused at the final one, which allows one to estimate the maximum energy contribution of the laser beam to the formation of Ni-Ti intermetallic compounds.

Results presented in
this paper are part of a work aiming to model the microstructure evolution of commercial steels
containing vanadium and niobium during austenitisation heat treatments.
This compound has already been identified by micro-diffraction in a low alloy steel [7] and in cast iron [16].
The present approach will also be extended to more complex quaternary alloys in a near future.

After such multicycle liquid phase mixing, the system revealed nano- and submicrocrystalline surface alloys based on TiAl and Ti3Al whose hardness, wear strength at room temperature, and heat resistance were higher than those of the initial titanium.
Our aim here is to identify and analyze the mechanisms of surface alloying of aluminum with titanium under intense pulsed electron beam irradiation.
Our X-ray diffraction analysis shows that irrespective of the film thickness and number of treatment cycles, the modified Ti–Al system features a multiphase surface structure which contains intermetallic compounds Al3Ti, Al2Ti, and TiAl3 as well as oxides TiO and TiO2 along with Al-based solid solutions (main phase) and α-Ti.

Lead-free solder alloys are now mainly used in the industry as electrical interconnects to fulfill the safety and health regulation [6–10].
Furthermore, Alam et al. investigated the variations in mechanical and microstructure behaviour of several lead free solder alloys subjected to high temperature aging.
The physical analysis founded the grain coarsening, intermetallic compounds volume increase, and the grain boundaries growth [9], [10].
