Definitions
- Non-hardenable aluminum alloy as semi-finished product for structures
- the present invention relates to the composition of alloys, in particular naturally hard semi-finished alloys, which are to be used in this form as material for structures.
- Naturally hard aluminum alloys as semi-finished products for structures are used in metallurgy, but especially as an AMg6 alloy, which contains the following (% by weight):
- a naturally hard aluminum alloy that is used as a semi-finished product for structures also belongs to the prior art as a prototype with the following chemical composition (% by weight):
- Cerium 0.001 - 0.004 aluminum rest This known alloy shows insufficient static and dynamic strength with high workability during the manufacturing process, high corrosion resistance, good weldability and high operability under low temperature conditions.
- the invention relates to a new, naturally hard aluminum alloy for semifinished products which, in addition to magnesium, titanium, beryllium, zircon, scandium and cerium, additionally consists of manganese, copper, zinc and an element group containing iron and silicon in the following composition of the components (% by weight) , where the ratio between iron and silicon is in the range of 1 to 5:
- Zinc 0.05 - 0.15 including iron and silicon
- the alloy according to the invention differs from the conventional alloy in its additional content of manganese, copper, zinc and an element group containing iron and silicon, the components having the following ratio (% by weight) and the ratio of iron and silicon being between 1 and 5 got to:
- Zinc 0.05 - 0.15 including iron and silicon
- the technical effect is an improvement in the static and dynamic strength properties of the alloy, which increases the service life and
- the alloy is more of a ductile matrix consisting of a mixed crystal of dissolved magnesium, manganese, copper and zinc in aluminum.
- Precipitates from finely divided intermetallic particles containing aluminum, scandium, zircon, titanium and other transition metals found in the alloy ensure both the high static strength of the alloy and good resistance to crack propagation under alternating stress.
- the setpoint of the iron-silicon ratio optimizes the morphology of the solidification-derived primary intermetallic compounds, which consist primarily of aluminum, iron and silicon and improve the static strength of the alloy while maintaining its dynamic strength and plasticity.
- composition 1 Using aluminum A85, magnesium MG90, copper MO, zinc TsO, binary master alloys such as aluminum titanium, aluminum beryllium, aluminum zirconium, aluminum scandium, aluminum cerium, aluminum manganese, aluminum iron and silumin as an additive prepares the melt in an electric furnace, followed by 165 x 550 mm large and flat cast blocks of the alloy according to the invention with minimum (composition 1), optimal (composition 2) and maximum (composition 3) ratio of the components - including the ratios which go beyond the current restrictions the components (compositions 4 and 5) and the conventional alloy (composition 6)
- scrap from aluminum-magnesium alloys can be used as an additive.
- the cast blocks were homogenized and machined to a thickness of 140 mm. Then they were hot rolled at a temperature of 400 ° C to a thickness of 7 mm and then cold rolled to a thickness of 4 mm. The cold rolled sheets were heat treated in an electric furnace. The heat-treated sheets served as test material.
- Table 2 shows that the alloy according to the invention has a higher static and dynamic strength than the conventional one. This enables one to reduce the weight of the structures made of the alloy according to the invention by 10 to 15% in order to reduce operating costs, which is particularly important for the aircraft industry.
- the alloy according to the invention can be used as a base material in welded structures and as a filler material for welded joints.
