abstract – aluminium 7075- t651 alloys are widely used in the production of light weight structures requiring a high strength to weight ratio and high corrosion resistance. the effect of processing parameters on fatigue life of 7075- t651 aluminium joints produced by friction stir welding was investigated in the present study. welding samples were made by employing rotating tool speed of 770, 9...

gears are one of the most critical components in power transmission system of an automobile and also many rotating machinery. many studies have been conducted on optimum gear design. the main objective is to design different aluminium metal matrix composite spur gears before and after optimization. aluminium metal matrix material composites are preferred mostly due to their low density. also th...

ABSTRAK Aluminium merupakan logam yang paling banyak digunakan setelah baja, dengan karakteristik utamanya adalah ringan (berat jenis = 2.7 g/cm3), memiliki konduktivitas panas dan listrik tinggi, ketahanan korosi baik. Penggunaan aluminium menempati urutan kedua besi baja sebagai bahan untuk komponen industri otomotif, salah satu penggunaanya yaitu berupa pada mobil. seri 7075 mana sifat baik ...

2014 A summary is given of data obtained from neutron diffraction experiments on heavy water at elevated pressures and temperatures using three different types of pressure vessel. The pressure vessels were manufactured from (i) hard steel (EN24T), (ii) titanium-zirconium null alloy, and (iii) autofrettaged aluminium alloy (7075-T6). In cases (i) and (ii), hydraulic pressures up to 6 kbar were a...

Aluminium matrix composites (AlMCs) of AA7075 aluminium alloy reinforced with 0.5 and 1 wt.% multiwall carbon nanotubes (MWCNTs) were fabricated powder metallurgy techniques using three different mechanical milling strategies, varying the energy stage in which reinforcements added to pre-alloyed powders. In this paper, we focus on influence these parameters dispersion MWCNTs. Characterization o...
