Scandium-alloyed aluminum alloys
Metal Science and Heat Treatment, 1992The basic principles of alloying of aluminum alloys with scandium are: it is desirable to add scandium to aluminum alloys in a quantity from 0.1 to 0.3% together with zirconium (0.05–0.15%), which strengthens the positive influence of scandium on the structure and properties of alloys; the greatest effect (that is, the positive influence on mechanical ...

Alloying Aluminum Alloys with Scandium
Metal Science and Heat Treatment, 2017Methods and procedures are discussed for more economic and effective use of scandium for alloying aluminum alloys. Specifically, it is recommended to introduce scandium and zirconium into aluminum alloys in a 1 : 1 ratio instead of the usual 3 : 1 with the same overall element content.

Inoculation Treatment of an Additively Manufactured 2024 Aluminium Alloy with Titanium Nanoparticles
Acta Materialia, 2020Considerable studies on metal selective laser melting (SLM) have proved the necessity to refine microstructure parts fabricated by SLM in order to eliminate property anisotropy, hot-tearing and to increase the SLM-processability.

Alloying with Silicon and Copper in Aluminum Alloys
Materials Science Forum, 2007The main aim of the metallurgical investigation was to enhance our understanding of the role Cu and Si have on the development of shrinkage porosity in the as-cast structure, which in turn can affect high cycle fatigue (HCF) properties of Al-9Si-1Cu (W328) and Al- 7Si-4Cu (W319) alloys.

Multiplicity of dislocation pathways in a refractory multiprincipal element alloy
Science, 2020Pathways for ductility Alloys containing multiple elements can be very strong but often suffer from poor ductility. F. Wang et al. found that different mechanisms accommodated plasticity in a molybdenum-niobium-titanium multiprincipal element alloy (see ...

Complex alloying of titanium alloys
Metal Science and Heat Treatment, 19751. The effectiveness of complex alloying was established, in which the strength of both the α and β solid solutions increases, and the difference between their strengths decreases. This leads to more even plastic deformation and more complete utilization of the strength of the α and β phases. 2.

Publisher Summary An alloy is a substance that has metallic properties and is composed of two or more chemical elements, of which the primary one is a metal. Homogeneous alloys consist of a single phase and mixtures consist of several phases. There are three possible phases in the solid state: pure metal, intermediate alloy phase or compound, and ...

Mechanical alloying of AlTi alloys
Materials Science and Engineering: A, 1990Abstract Mechanical alloying has been used to mix elemental powders of aluminium and titanium and to produce mixtures of aluminium and Al 3 Ti phases during heat treatments for consolidation. Alloy concentrations of 12.5–26 at.% Ti have been covered, corresponding to alloys containing 50–100 at.% Al 3 Ti after reaction.
