Influence of cryogenic treatment on mechanical properties of cemented carbides [PDF]

, 2016
Cemented carbides, often referred to as hardmetals, are materials composed by two major phases: a carbide ceramic phase and a binder metallic one. The metallic binder maintains the ceramic grains together in an interpenetrated network structure.

Cryogen Characteristics and Its Treatment.

TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1993
In every stage of experiment in low temperature physics and cryogenic engineering liquid helium and nitrogen are used popularly, but they are not necessarily used properly. The proper usage of these cryogen is reconsidered in this article by investigating the thermophysical property differences in latent heat, thermal conductivity, enthalpy and so on ...
