Abstract
A lot of slag was produced by ancient production processes such as smelting, melting, and refining. Iron slag has information that can be used to determine the characteristics of the site, the iron-making process and manufacturing date, but there is a limit to reading information through visual observation and nondestructive.....

Abstract
Metallurgical remains such as crucible, mould, slag and tuyere are generated in the production of bronze. The analysis of slag in particular can be used to identify the raw materials, processes and environments (temperature and condition) employed in the bronze fabrication . The Gwanbuk-ri site in Buyeo is known as..... More

Abstract
Fe-36%Ni steels have a much lower thermal expansion coefficient than stainless steels and aluminum alloys for low temperature. They also have moderately high strength and good toughness at cryogenic temperatures because of its stable austenite phase. These excellent low temperature characteristics make this alloy attractive for cryogenic applications such as..... More
