The aim of this paper is to present the simulation and experiment of the welding butt-joint aluminum alloys to low carbon steel using Visual-weld software and the metal inert gas (MIG) welding process.
It includes bottom plates (AA5052 alloys) and low carbon steel plates (SS400 steel) with the same size 200x70x5mm.
All experiments were performed on aluminum sheet A5052 alloys and SS400 steel sheet with a thickness fixed of 5mm.
This is good indicator of how the alloys’ density in the welding bead is affected during the welding process.
It is typically used for estimating the alloys’ content along with the uniformity of the welding bead during the welding process.

The aim of this research was to study the recycling process and the feasibility to smelt the spent nickel catalyst for the production of nickel alloy or ferronickel.
Introduction Nickel is commercially important as being mainly used as high performance alloys, key alloying element for stainless steel production and electroplating to improve tribological properties and decoration on many types of material surfaces.
The hydrometallurgy process involves acid leaching to obtain nickel in the solution prior to extraction by using different techniques, giving mostly nickel compounds [6-9].
X-ray diffractometer was used to determine phases and compounds (Using Bruker model D8 ADVANCE Cu Ka at condition 40 kV, 40mA).

The combination of e. g. aluminium with steel allows to produce hybrid compounds with wear-resistant functional surfaces and reduced weight.
For this reason, the aim of the Collaborative Research Centre 1153 is to realise new process chains to produce hybrid solid components with load-adjusted properties using semi-finished workpieces joined prior to forming [1].
In [4], the feasibility of the co-extrusion of asymmetric aluminium-titanium compound profiles was shown.
Thus, the maximum tensile strength of the specimens testing the weld seam complies with the tensile strength of the alloy.

Nitriding, oxidation and carburizing are among the most popular thermo-chemical treatments aiming to improve the tribological properties of billet Ti-alloys.
The evolution of the surface hardness of the titanium alloys studied in response to the GN temperature and time is similar for all Ti-alloys.

The disadvantages of the conventional twin-roll caster for aluminum alloy are low casting speeds and limited choices of alloys that are castable by this processing.
These alloys are expensive for regulation of Fe content to get excellent formability.
The plate of 5000 series of aluminum alloys is used for the structural parts.
However, the twin roll caster for aluminum alloy also has disadvantages, including low casting speed and limitations on alloys that can be cast.
It’s aim to get high roll speed.

The latter is widely used today for the design of new alloys based on powders (iron) to meet industrial requirements in strength and wear characteristics.
This study aims to develop an iron-based alloy for use in a highly stressed environment [5].
II-Experimental: For the study of the influence of tungsten, four alloys were developed with different tungsten content (5%, 10%, 15% and 20%).
Hardness: The microhardness HV0.1 is obtained for the different alloys using a computer controlled DM2D AFFERI.

The aim of our work is to synthesize molybdenum nitride by a simple, low-temperature route.
Fourier transform infrared spectra of the polymer and its pyrolyzed compounds in KBr pellets were carried out using a Thermo-Nicolet Nexus-870 FT-IR spectrometer.
The pyrolyzed compounds were characterized by FTIR and XRD.
X-ray diffraction curves for the pyrolyzed compounds at 400 oC and 800 oC are shown in Fig. 3 and 4.
