Microstructure of Hypereutectic silumin at high-speed solidification

Физика металлов и металловедение / Physics of Metals and Metallography
The paper presents the results of a study of the microstructure of Al-20.1Si-0.2Fe and Al-21.3Si-0.8Mg-0.5Fe-0.3Mn-0.6Ni-1.4Cu alloys (the concentration values of the elements are given in wt%) obtained by ultrafast quenching from the melt.

Laser surface alloying of silumin

Metal Science and Heat Treatment, 1995
Laser alloying is an effective way to increase the surface hardness and wear resistance of materials, including aluminum. The effect of laser alloying on the structure and hardness of silumin AL30, which is used to produce engine pistons operating at high temperatures, is an interesting subject for study.

Tribotechnical Study of Antifriction Silumin AlSi15Cu3

Journal of Friction and Wear, 2020
In this paper we performed comparative studies of the tribological properties of the AlSi15Cu3 antifriction silumin and BrOTsS5-5-5, BrOF10-1, and BrAZh9-4 bronzes during friction in the I-20A lubricant environment in a wide range of sliding speeds and test pressures.

Metalographic study of burning of silumin

Metal Science and Heat Treatment, 1984
1. Burning of Al−Si-alloys which develops as coalescence of silicon is due to development of silicon and hydrogen atom diffusion, i.e., permanent impurities in aluminum alloys. The rate of the process is governed by hydrogen content. 2. The more hydrogen Silumin contains the less is the effect of external influences (temperature, soaking

Treatment of Al-7%SiMg Silumin with an Exothermic Mixture Containing NaNO3 and NaClO3

Materials Research Proceedings
. Hypoeutectic silumins are one of the most popular groups of casting alloys. A problem with the use of hypoeutectic silumins is their microstructure, which negatively impacts their performance.

Fractographic features of the fracture of silumins

Metal Science and Heat Treatment, 1981
1. Fracture of silumins in static loading starts with the formation of voids around the silicon particles. The size of the voids is comparable with the size of of the particles, which is responsible for the close relationship of the fracture relief to the degree of dispersion of the structure. 2.

Die Casting Defects of Castings from Silumin

Applied Mechanics and Materials, 2014
The production of die castings cast into a metal mold has in recent years achieved an expansive growth in the volume as well as the range of production and that is particularly in aviation and automobile industry. A primary criterion for achieving reliability, efficiency and quality of production is to ensure minimization of the castings defects ...
