As popular aluminum alloys, the 5xxx Al-Mg series, such as 5050 and 5052, etc., are widely used in applications such as automobile, pressure vessels, armor plate, and components for marine and cryogenic service. In this, as in all non-heat-treatable aluminum alloys, the weld metal zone is considered to be the weakest part of the joint and is the location of failure when the joint is loaded in t...

Aluminum alloys show a low weight, relatively high specific strength, good corrosion resistance in neutral environments and high electric and thermal conductivity. It makes them of interest for production of various functional components in aerospace and automotive industry. Wrought alloys generally have good formability and they are processed by common technologies, such as extrusion, forging,...

Control of microstructure parameters that affecting the Al-Ti-C master alloys grain refining efficiency is leading to improve the aluminum grain refinement. This study was an attempt to produce Al-Ti-C master alloys that provide these controlling factors with relying on the solute effect theory. The produced master alloys were examined by using scanning electron microscopy (SEM), energy-dispers...

Knowledge of statistical characteristics of mechanical properties is very important for the practical application of structural materials. Unfortunately, the scatter characteristics of magnesium alloys for mechanical performance remain poorly understood until now. In this study, the mechanical reliability of magnesium alloys is systematically estimated using Weibull statistical analysis. Intere...

Al-Ti-B master alloys are widely used in the aluminum industry as grain refiners for the control of the microstructure of the aluminum alloys. The SHS (self-propagating high-temperature synthesis) is an ex situ method that uses exothermic reactions to sustain the chemical reaction in a combustion wave. The advantages of SHS are the low energy requirement, simplicity and product purity. However,...

Aluminum and its alloys have a lot of industrial applications due to their appropriate physical and chemical characteristics. However, those present a modest mechanical performance. One method to improve its strenght is the addition of hard insoluble particles as: carbides (Al4C3, TiC), oxides (Al2O3) or nitrides (TiN, AlN), which can difficult the dislocation movement at atomic level, resultin...

the application of ai-li alloy in aerospace and aircrafts industries have a promising future due to its lower density and a comparatible mechanical properties to the other aluminum alloys. the major problems encountered with parts made of al-li alloys, include segregation and brittleness. the presence of a precipitation free zone (pfz) and also the concentration of some elements such as k,na,o,...

It is considered to be available in reducing the weight of automobiles that the aluminum alloy is applied to manufacture them. The spot welding of aluminum alloys is difficult because of high welding current and small electrical resistance. It is necessary to clarify the relation between the nugget formation and the welding conditions. In this study, the relation between the spot welding condit...

One of the major aims of the modern materials foundry industry is the achievement of advanced mechanical properties of metals, especially of light non-ferrous alloys such as aluminum. Usually an alloying process is applied to obtain the required properties of aluminum alloys. However, the presented work describes an alternative approach through the application of vibration treatment, modificati...
