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.

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.

Electrolyte Chemistry Enables Simultaneous Stabilization of Potassium Metal and Alloying Anode for K-Ion Batteries.

Angewandte Chemie, 2019
Alloying anodes are promising high-capacity electrode materials for potassium-ion batteries (KIBs). However, KIBs based on alloying anodes universally suffer from rapid capacity decay due to the instability of K metal and large volume expansion of ...

Alloying Aluminum Alloys with Scandium

Metal Science and Heat Treatment, 2017
Methods 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.
