Electron backscatter diffraction reveals the microstructure of metals and alloys

EBSD ﬁnds signiﬁcant application in the study of metals and alloys, oﬀering advantages over conventional techniques by providing a wide range of characterization possibilities in a single method. The microstructure of metals, alloys, and composites plays a crucial role in determining their desired properties, making EBSD an essential tool for their characterization and understanding the impact of diﬀerent processing steps.

In manufacturing processes like joining, deformation, powder metallurgy, and additive manufacturing, EBSD is a powerful technique for characterizing and evaluating the inﬂuence of parameters and production stages on the ﬁnal microstructure of components. It is also widely used to assess the eﬀects of surface heat treatments and in situ mechanical tests.

Speciﬁc industrial applications in which EBSD is regularly employed to enhance material quality and production processes

Aluminum sheets used for beverage cans or food containers require controlled texture to ensure smooth surfaces and suﬃcient strength. EBSD is utilized to assess and optimize the texture, ensuring the production of high-quality cans with reduced material usage.

In the automotive industry, the latest generation of high-strength steels is employed to reduce vehicle weight and improve fuel eﬃciency. EBSD helps diﬀerentiate between diﬀerent phases (austenite, ferrite, martensite) and provides grain size and texture information crucial for optimizing the strength and performance of these steels.

Material quality and production processes

EBSD is widely used to understand failure mechanisms in metals. It can identify grain boundaries that are susceptible to corrosion and subsequent fracture. Grain boundary engineering (GBE), enabled by EBSD, can be employed to improve material properties by manipulating grain boundaries and enhancing corrosion resistance, creep resistance, and deformation behavior.

EBSD facilitates the study of dislocations and defects in metals, providing insights into deformation processes and their eﬀect on mechanical properties. This information is particularly valuable for optimizing processing conditions, such as heat treatment and cold working, in materials like aluminum alloys, where corrosion resistance and lightweight properties are crucial.
