Spark alloying of an AL9 alloy by hard alloys

Russian Metallurgy (Metally), 2015
The 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.

Scandium Alloying of Aluminum Alloys

Metal Science and Heat Treatment, 2020
Basic 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, 1992
The 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 ...

Casting alloys

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, 1992
Abstract 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), 2013
The 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.

Complex alloying of titanium alloys

Metal Science and Heat Treatment, 1975
1. 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.
