Abstract Scope |
Today, state-of-the-art characterization techniques available in the laboratory and at national user facilities are enabling unprecedented, multiscale in-situ/ex-situ studies of structural alloys and new insights into processing-microstructure-property-performance relationships. In this work, transformation- and/or twinning-induced plasticity, TRIP or TWIP, respectively, are highlighted in structural metallic alloys that achieve desirable strength/ductility combinations, from quasi-static to dynamic deformation. For example, microstructures during/after deformation, including in-situ synchrotron x-ray imaging and diffraction during high strain rate testing up to 2 x 10^3 s^-1, along with complementary post-mortem characterization, reveal evidence of TRIP and TWIP in metastable titanium and multi-principal element alloys. These deformation mechanisms can be tailored to design the microstructures, properties and performance of structural metallic alloys for engineering applications. |
