Abstract The characteristics and structural performance of a composite material’s properties are better than those its component parts because It comprised pair or more insoluble, chemically separate stages. functioning alone. ‘Metal-Matrix’ composites materials that have been produced from metals ceramics had fibers particles incorporated into them to enhance their physical characteristics. fa...

The critical energy release rate defined as Gc = 2γ + γp (where, γ is the cohesive energy and γp is the plastic work) is widely used as a macroscopic fracture criterion. During embrittlement of Aluminum by Gallium, impurity segregation is localized to a small region along the grain boundary and the bulk plastic properties is unaffected. Yet, the critical energy release rate (which is predominan...

Cavitation erosion prediction and characterization of cavitation field strength are of interest to industries suffering from cavitation erosion detrimental effects. One means to evaluate cavitation fields and materials is to examine pitting rates during the incubation period, where the test sample undergoes localized permanent deformations shaped as individual pits. In this study, samples from ...

In this study, compressive and tensile strain in Al7075 plate have been measured by synchrotron energy-dispersive X-ray diffraction (EDXRD) conjunction with 4-point bending test under various load up to 1000 lbs(453.6 kg). The are determined stress related interplanar spacing variation at 111 peak reflection which is considered atomic level measurement. specimen initially shows elastic behavior...

The objective of this research is to study the effect Zr on L-PBF processability, microstructure, and microhardness an AlZnMgCu-Zr alloy. Two AlZnMgCu-0.5 1.5 wt% pre-alloyed powders were produced by casting followed gas atomization. In addition, excess Mg Zn was added target compositions compensate for vaporization during L-PBF. as-atomized as-built heat treated specimens characterized via sca...

Most aluminum alloys, especially the 7xxx series, are incompatible with laser additive manufacturing due to many factors. In-situ process monitoring technology offers an excellent opportunity for understanding and control, which improves component quality repeatability of AM. In this study, emission spectroscopy plume imaging were utilized monitor understand laser-directed energy deposition Al7...

About 50% of metals used in Aerospace industries are Aluminium and Titanium alloys, Alloys such as Ti6Al4V, AL-7175, and AL7075 are used extensively in space vehicles, aviation, and automotive industries for having enhanced mechanical properties like High strength to weight ratio, low Thermal Expansion and better Corrosion resistance. Comparison of properties Aluminium and Titanium alloys shows...

Metal matrix composites (MMCs) play a crucial role in the aerospace, automotive and mineral processing industries. The properties of aluminum (AMC) that are renowned for their high strength, good stiffness excellent thermal conductivity can be enhanced by incorporating various reinforcements. In this investigation, Al7075 alloy with TiC (3, 6, 9 wt.%) reinforcements was processed via stir casti...
