Tantalum alloy
Tantalum Alloys
Tantalum alloys are materials of high melting point, low vapor pressure, and high electrical resistivity. As such, these alloys have numerous uses in a wide array of industrial and commercial applications. One variety of tantalum alloys, known as refractory metals, are among the m......
eutectic core
The Core of a Common Crystalline Group
Crystalline group is a group of particles which share a common structure and atomic arrangement. It is distinct from noncrystalline materials which lack the regular crystal structure of crystalline solids. Crystalline substances typically form regular lattic......
primary austenite
General Introduction
Austenite (γ-iron) is an important phase of iron and its alloys, and is an important component in the process of forming steel. Austenite generally has a body-centered cubic crystal structure, and its crystal lattice is composed of iron atoms, which can change with temperatu......
Factors Affecting Slowly Cooling Dendrites of Austenite
Factors That Influence Austenite Cooling Transformation
Austenite cooling transformation is the process through which the austenite phase structure in metals and alloys is transformed from the high temperature form to the lower temperature form. During cooling, the austenite phase forms a coarse ......
