WEDM is one of the important variants of electrical discharge machining (EDM) which uses the thermal energy generated between the electrodes for machining the electrically conducive materials. This method has been successfully implemented in common materials like aluminum, stainless steel etc., But its application in super alloys like Ti6Al4V is still under investigations. This paper reviews th...

Results of internal friction measurements on the commercial aluminum-magnesium alloys 5052,5086 and 5486 are reported here over the temperature range 50 mK to 300 K, and compared with published data on alloy 5056. Effects of heat treatment and explosive bonds on the internal friction are evaluated. The quality factor of proposed multi-layer aluminum-alloy spherical resonant-mass detectors of gr...

The formation of twinned dendrites (feathery grains) in binary Al–Zn, Al–Mg, Al–Cu and Al–Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G 100 K cm , v 1 mm s , and with slight natural convection in the melt. The influence of the solute element nature and content has been found to be of less importance than previously reported since fea...

The recent development of metallic alloy systems which can be processed with an amorphous structure over large dimensions, specifically to form metallic glasses at low cooling rates ~;10 K/s!, has permitted novel measurements of important mechanical properties. These include, for example, fatigue-crack growth and fracture toughness behavior, representing the conditions governing the subcritical...

High-strength aluminum alloys are of increasing interest to the aerospace and automotive industry for critical high-strength components. B-pillars and door beams being of particular interest to the automotive industry Refill friction stir spot welding (RFSSW) offers an attractive means of joining these difficult-to-weld alloys since bulk melting is avoided and no exit hole is left. In this stud...

Aluminum-rich intermetallic compounds and alloys are important for their technological applications and scientifically interesting for their complex structures such as quasicrystals. Detailed knowledge of interatomic interactions can help explain structural and mechanical properties of these systems. The first paper of this series @Phys. Rev. B 56, 7905 ~1997!# derived first-principles interato...

The low hardness and poor tribological performance of aluminum alloy as moving component greatly restricts their wide applications in automotive fields. In this letter, an attempt to deposit gradient Ti/TiN/Si/(TiC/a-C:H) multi-layer on aluminum alloy is thus effectively performed by a combined arc ion plating and magnetron sputtering process based on the concept of involving coatings with a fu...

A modified impeller mixing coupled with chill casting technique was used for the preparation of immiscible alloys. In this paper Al-Fe binary alloys was chosen for this study. This binary system shows the miscibility gap at specified concentration and temperature. The electrolytic grade iron powder of 300mesh size was dispersed in the melt of commercially pure aluminum. The iron content in the ...
