Aluminum Matrix Composite Material

Friction stir welding of butt joints of aluminum-matrix dispersion-strengthened composite materials is considered. It is shown that with an increase in the content of strengthening SiC particles, the range of welding modes that ensure the formation of a joint without defects is significantly narrowed. It was found that under cyclic loads, welded joints begin to fail from the face of the weld. Keywords: friction stir welding, aluminum matrix dispersion-hardened composite material, mode, structure, roughness, strength. [email protected]

AbstractThe fabrication of a durable and usable aluminum matrix composite poses a challenge because it is hard to obtain defect-free welds by using conventional fusion welding methods. The development of friction-stir welding (FSW) provides improved microstructure modification. As there are no melting problems associated with it, liquid-solid reactions are eliminated. The objective of this study was to attempt FSW of an AA6061 alloy reinforced with an iron-based metal and to determine the properties of the joints. The effects of FSW parameters, especially the tool rotation speed, are presented first. Then, the application of the technique in manufacturing and microstructure modification of particle-reinforced composite materials is discussed. Finally, interfacial microstructural changes and the associated mechanical properties are evaluated.

The properties and structure of the joints of the layered composite material based on aluminum alloys 1570— 1915—1570, made by resistance spot welding, automatic argon arc welding and friction stir welding are presented. The spot, lap and butt joints are made. The strength of the joints made by automatic argon arc welding with the AMg63 fi lling wire was 333...377 MPa at 180° bend angle. The butt joints obtained by the friction stir welding have strength factor of 0.90...0.92 from the strength of the base metal.

Aluminum Matrix Composite Material

The research involves studying the high-temperature chemical interaction of the Al-SiO2 system components. The high-temperature interaction of molten aluminum and silicon dioxide results in formation of aluminum matrix composite material containing silicon microparticles. The predominant linear size of silicon microparticles amounts to 3 - 5 microns, their mass fraction in the composite reaches 29 %.
