Ti-6Al-4V (UNS designation R56400), also sometimes called TC4, Ti64, or ASTM Grade 5, is an alpha beta titanium alloy with a high specific strength and excellent corrosion resistance. It is one of the most commonly used titanium alloys and is applied in a wide range of applications where low density and excellent corrosion resistance are necessary such as the aerospace industry and biomechanical applications(implants and prostheses).

A Novel Approach for Rapid Material Library Generation Using Laser-Remelting
Gaag, T.*, Heidowitzsch, M., Galgon, F., Körner, C., & Zenk, C. H.*
Traditionally, development of new metal materials has relied on trial-and-error methods, which are cost and time-demanding.
This research contributes to increasing the efficiency of alloy design and development in material science by presenting a novel approach to rapidly generate materials libraries using InssTek’s technology.
Experiment
In this study, researchers conducted experiments to generate and characterize a material library of CrCoNi, employing the surface laser-remelting technique. Composition and mechanical properties of the successfully created CrCoNi material library were evaluated using EPMA and microhardness testing.
Conclusions
The proposed method shows promise to be employed as a high-throughput screening tool aiming at the investigation of bulk material properties of complex systems. And the potential of the material library was demonstrated through changes in phase stability and microhardness.
