Liquidmetal Technologies is committed to providing the highest quality parts to customers, which means careful attention and regulation of the end-to-end materials and fabrication processes.

As a recent breakthrough in engineered materials technology, bulk metallic glass alloys require extremely high quality standards to ensure reliability and repeatability in part performance. Many of the analysis tools that are used in traditional metallurgy can be used to assess the quality of Liquidmetal processes, but often in ways as unique as the alloy itself.

Liquidmetal Technologies uses a wide variety of tools to track the quality of its products, from initial alloy production to final part performance.

Chemistry: Since the material properties of Liquidmetal alloys are inseparably linked to its glassy structure, the alloy composition, which dictates its glass forming ability, is of crucial importance. Liquidmetal alloys have incredibly precise compositions and extremely low levels of contaminants such as oxygen.

Differential Scanning Calorimetry (DSC): A technique for studying the heat release associated with material phase transitions, which can be used to extract information about volumetric amorphous content of as-cast parts.

Optical Microscopy: High quality bulk metallic glass parts can be identified by their uniquely featureless surfaces when an ultra-high polished is applied to a specimen.

Mechanical Strength: As-cast mechanical properties can also be used to determine the consistency and reliability of the alloy and processing method.
