Hardness mapping of a DP980 steel sample
6 Jul 2023In this application note, Bruker Nano utilizes hardness mapping to characterize the two phases of a dual-phase (DP) steel sample. Advanced DP steels are important new high-strength steel products being developed for the automotive industry. Their microstructure typically consists of a soft ferrite phase with dispersed grains of a hard, substantially stronger, martensite phase. While conventional DP steels exhibit a low-yield strength phase combined with a high-strength phase, new advanced DP steels use solid-solution hardening in the ferrite phase to increase the yield strength. These enhanced properties make DP steels suitable for automotive structural and safety parts, such as longitudinal beams, cross members, and reinforcements.

Mechanical TestingMechanical testing explores the elastic and inelastic nature of a material when force is applied. A mechanical test shows whether a material is suitable for its intended application by measuring hardness, tensile strength, elongation, elasticity, and fatigue limit.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.ProfilometersProfilometers are instruments used to measure a surface's profile, in order to quantify etch depth, deposited film thickness, and surface roughness. They operate in either contact or non-contact modes and may use optical or stylus techniques to make the actual measurements.Light MicroscopyLight microscopes or optical microscopes are used to visualize microscale objects under magnification, including cells, clinical specimens and materials. Lab equipment for light microscopy includes confocal microscopes, fluorescence microscopes, zoom and stereo microscopes. Microscope slides and imaging reagents are available for visualizing samples, as well as various microscope stages and incubators for large or temperature-sensitive samples.

Types of electron microscope include scanning electron microscopes (SEM), transmission electron microscopes (TEM), scanning transmission electron microscopes (STEM) and cryo-electron microscopes. Focused ion beam (FIB) microscopes are useful for modifying or milling a sample surface with nanometer precision, as well as imaging.
