Spark alloying of an AL9 alloy by hard alloys
Russian Metallurgy (Metally), 2015The phase compositions of spark coatings of Kh12M steel with a VT1-0 (titanium) alloy and T15K6 and T30K4 hard alloys are studied. It is shown that the TiC titanium carbide forms in all cases and tungsten carbide decomposes with the formation of tungsten in a coating. These processes are intensified by increasing time, capacitance, and frequency.

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.

Scandium Alloying of Aluminum Alloys
Metal Science and Heat Treatment, 2020Basic physical metallurgy principles of alloying of aluminum alloys with scandium are considered and the fundamentals of the production of deformed semiproducts from these alloys are discussed. The discussion is based on the expected widening of the range of application of deformed semiproducts from scandium-alloyed aluminum alloys.

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 ...

Dental Clinics of North America, 2004
Although the role of dental casting alloys has changed in recent years with the development of improved all-ceramic materials and resin-based composites, alloys will likely continue to be critical assets in the treatment of missing and severely damaged teeth. Alloy shave physical, chemical, and biologic properties that exceed other classes of materials.

TOPHEL ALLOY, NIAL ALLOY, NICROSIL/NISIL ALLOYS, 20 and 19 ALLOYS
Alloy Digest, 1992Abstract TOPHEL Alloy and NIAL Alloy are respectively the positive and negative thermoelements for ISA Type K thermocouples. NICROSIL/NISIL Alloys are respectively the positive and negative thermoelements of ISA Type N thermocouples. Thermocouples of 20 and 19 Alloys have the advantage of freedom from green rot preferential oxidation ...

Alloying of aluminum-beryllium alloys
Russian Metallurgy (Metally), 2013The existing phase diagrams of Al-Be-X alloys, where X is an alloying element, are analyzed. Element X is noted to poorly dissolve in both aluminum and beryllium. It is shown that the absence of intermetallic compounds in the Al-Be system affects the phase equilibria in an Al-Be-X system.

Calcium-alloyed magnesium alloys
Metal Science and Heat Treatment, 2009Mg - Al - Ca alloys positioned in the Mg - Al 2 Ca quasi-binary section are studied. It is shown that alloys of this system bearing the Al 2 Ca compound as a hardening phase can be used for developing structural alloys with elevated strength at 170°C and that the strength characteristics of the Mg - Al - Ca alloys can be improved by adding manganese.

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.
