Nickel-Chromium-Iron Alloys. There are basically two groups of alloys: Ni – Cr – Fe alloys with excellent strength at high temperature and the ability to resist oxidation, carburisation and other types of high-temperature corrosion. The best-known is alloy 800 (UNS N08800) and its variants 800H (UNS N08810) and 800HT (UNS N08811).

North Korea. The world’s newest nuclear weapon possessing state, North Korea withdrew from the NPT in 2003 and conducted its first nuclear test in 2006. It has developed sophisticated nuclear weapons and ballistic missiles despite international condemnation, and diplomatic efforts to denuclearize the country have thus far been unsuccessful.
Alloy | Definition, Properties, Examples, & Facts | Britannica
alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel. Alloys are usually produced by melting the mixture of ingredients. The value of alloys was discovered in very ancient times; brass
Dose-dependency of contact resistance and sheet resistance of B-implanted emitters for N
2023315· The contact resistance and sheet resistance of a screen-printed fire-through Ag/Al paste metallization to the implanted B emitters of n-type crystalline Si solar cells were investigated as a function of B doses in the range of 2 × 1014 to 5 × 1015 cm−2 at a fixed implantation energy of 10 keV. For B emitters implanted with a B dose of > 2 ×
