Al-Cu-Zr MODIFYING ADDITIONS FOR ALUMINUM ALLOYS

The effect of small additions of zirconium and copper on the grain refinement of the Ak7 alloy and its structural components is considered. Additives were introduced both in the form of an experimental Al-Cu-Zr complex ligature and Al-Cu and Al-Zr binary alloys

Modification of Silumins with Complex Additives of Cu with Zr AND Cu with Ti

The modifying ability of the experimental Al-Cu-Ti, Al-Cu-Zr master alloys on the industrial alloy Al-7%Si-0.45Mg (A396, Ak7h) was evaluated and compared with the commercial Al-Ti-B master alloy. Modification was carried out in a bucket with a melt mass of 60 kg

Development of high-entropy eutectic alloys for structural applications

The systems AlCoFeNiTi, CoCuFeNiTi, AlCoCrFeNi are considered from the point of view of creating structural alloys with a eutectic structure

FORMATION OF Al-Y ALLOYS OF HYPOEUTECTIC COMPOSITION WITH SMALL ADDITIONS OF Sc AND Zr

The study was made of the effect of small additions of transitional additives and heat treatment on the structure and service properties of Al-Y hypoeutectic alloys

ANNEALING OF THE IRON-NICKEL ALLOY OF EXTRATERRESTRIAL ORIGIN AT THE SPINODAL DECOMPOSITION TEMPERATURE

The samples of Seymchan meteorite (PMG) were objects of the study. The effect of an-nealing on the structure of extraterrestrial alloy at a temperature of 400 °С was studied. The changes in the nanoscale structure of the iron-nickel alloy after annealing were not found.Исследование выполнено при поддержке Министерства Образования и Науки РФ (проект № 075-03-2020-582/4)
