The third group contents different exothermic reactions utilizing as the reactants various chemical compounds or using decomposition phenomena.
Bovinskaya classified SHS-derived materials into five different types, namely: (a) single phase solid solutions of metals in nonmetals; (b) binary compounds; (c) single phase solid solutions based on two or several refractories; (d) heterogeneous mixtures and (e) organic compounds.
SHS is especially useful for preparation of non-oxide ceramic powders like carbides, nitrides, borides, etc. i.e. compounds having generally rather low sinterability.
Composite materials in the AlN-g alon system prepared using SHS-derived powders posses advantaged mechanical, thermal, electrical properties [47] as well as high corrosion resistance against molten metals, especially nickel-based super-alloys [48].

At last, the experiments have been set up to verify the simulations.Nowadays, finite element method with software simulation can help engineers to predict the springback angle.Compare to the trial-and-error method, the FEM method can save a lot of time and money.It is important to minimise the springback angle and longitidianl strain in the roll forming porcess.The aim of this paper is to figure out the spring back angles with different materials in roll forming prcess and the influence of the factors on bow defect. 1.

Lithium is a common atom in technology, introduced into the composition of electrolytes [2] and scintillation crystals [3], electrodes in non-aqueous solvents or in vacuum systems, to increase the electrical conductivity, alloys strength and plasticity, as a polymerization catalyst, etc.
The yellow-orange flame is due to the combustion of lithium, sodium (impurities), and carbon compounds (due to evaporation and decomposition of the solvent).
Lithium hydroxide (LiOH) forms an alkaline environment The reaction lasted two days due to the gradual contact of water with the internal layers of the battery, which led to the slow dissolution of lithium and cobalt compounds.

Copper and its alloys represent a major center in the industry, alongside its wide applications in the electrical industries.
It is used in the manufacture of a number of useful alloys such as (Cu-Al), brass and bronze and in sea water applications due to its high resistance to corrosion [6,7].

The former process aims at complex shape parts.
Adaptability to the magnetic conductivity of workpieces: In the magnetic-abrading process, metal workpieces that can not be magnetized like titanium alloys, 1Cr18Ni9Ti or 38CrMoAlA, can not attract magnetic abrasives, and the free magnetic abrasives can only gather on the surfaces of the magnetic poles without pressure to the surfaces of the workpiece; thus, without the abrading action to the surface of the workpiece.

Ifante and Vidal [5] developed a theory aimed at the flow of material during the process.
Therefore, for obtaining FSW joints without defects is recommended to obtain a process temperature of 700-950°C, representing about 65-70% of the melting temperature of the compound material achievable by using appropriate technological parameters.
Another main direction of research is also aimed at establishing the optimal technological parameters of the type of structure and steel that is joined.

Corrosion of metals can be controlled by taking suitable preventive measures such as painting, plating, use of expensive alloys, use of inhibitors, etc.
Although, synthetic compounds have been proven to be good inhibitors in nature but most of these synthetic inhibitors are found to be toxic to the environment and the media.
Plant based inhibitors offer a number of advantages such as biodegradability, absence of heavy metals or other toxic compounds, availability and ease of processing [3 – 5].
The aim of this work is to investigate the neem leaf extract as a corrosion inhibitor of mild steel in 0.1M HCl using weight loss method.
