چکیده
The vacuum brazing of dissimilar Al 7075 and Al–25 Si alloy was investigated. filler copper foil with a thickness 20 μm, the temperature 560 °C held for 10 min. average shear strength brazed joint 26.4 MPa. layer found to be dissolved completely, interface had an irregular shape serrated border, indicating good metallurgical bonding between two alloys. However, factors which might cause deterioration were also observed, including formation intermetallic compounds such as MgZn2, Cu2Al Mg2Si, existence voids microcracks, coarsening grains in 7075, primary alloy.

Vacuum Brazing of Zirconium-Based Alloy and 321 Stainless Steel Using Titanium Based Filler Metal
Both Zirconium-based alloys and 321stainless steel are widely used as engineering alloys due to their good mechanical properties. Conventional fusion welding techniques for Zr alloys and stainless steel are not feasible due to the formation of brittle intermetallic compounds such as (Zr3Fe, ZrFe2 and Zr2Fe) and corrosion cracking. Brazing is one of the most wide...
متن کاملMechanical Properties and Spring -Back Investigation in Creep Age Forming Process of 7075 Al Alloy
Creep age forming (CAF) process is a novel metal forming method with major benefits including improved mechanical properties and cost reduction for aviation industry applications. CAF happens due to creep phenomenon and stress-release during the artificial aging of heat-treatable aluminum alloys. In this work, the creep age forming of 7075 Aluminum alloy at 120, 150 and 180 °C for 6, 24 and 48...

In the present research, thixoforming route was carried out in order to enhance the microstructural features of LM28 piston alloy. Typical microstructure of this alloy was composed of coarse, polygonal primary silicon particles, eutectic matrix and intermetallic phases. Thermal analysis was carried out to study the solidification path of the base alloy and determine the major arrest temperature...
متن کاملRefining Mechanism of 7075 Al Alloy by In-Situ TiB2 Particles
The nucleation undercooling of TiB₂/7075 Al matrix composites, the microstructure observed after solidification at different cooling rate, and the size and distribution of TiB₂ particles were investigated. The experimental results have shown that the grain sizes of TiB₂/7075 Al matrix composites firstly decreased, then increased, and finally decreased again with the increase of TiB₂ content. Th...
