Thermal analysis in the Metals / Alloys Industry

Metals used as materials must fulfill certain conditions depending on the intended use. Maximum durability and length of service of metals depends on their properties such as hardness, strength, thermal expansion, thermal conductivity or their oxidation and or corrosive behaviors.

These are often alloyed with other semi or non-metals, since this severely restricts the usability of pure metals. These mixed metals, also called alloys, are characterized by improved material properties and thus greatly expand the range of applications.

Physical metrology such as differential thermal analysis (DTA PT 1600), heating microscopy (L74 optical dilatometer), differential scanning calorimetry (DSC PT 1600) or thermogravimetry (STA PT 1600) allows one to analyze the metallurgical behavior of metals and alloys with respect to the following issues:

How well does a metal conduct?
How do certain temperatures affect a metal or an alloy?
How does the specific heat change with increasing temperature?
At what temperature does the oxidation of the metal surface begin?
When is a metal alloy in phase equilibrium?

Phase transitions, the point of crystallization, the change of states of matter and the thermostability of starting materials for sheets, beams and other metallurgical products can also be studied by physical measuring techniques. The same applies to specific heat capacities, coefficients of linear expansion, and the melting point.

LINSEIS manufactures and sells thermoanalytical measuring systems, which can be used in many other sectors in addition to metallurgical fields. Key areas of application include research, product development and quality control.
