TL;DR: In this paper, the authors systematically investigated the stress-strain behavior of ferrite and bainite with nano-sized vanadium carbides in low carbon steels, and the results showed that nano-size carbides may act as sites for dislocation multiplication in the early stage of deformation, while they may enhance dislocation annihilation in the later stage.

TL;DR: In this article, the (Nb)/Nb3Si eutectic alloys in binary and ternary systems were unidirectionally solidified in an optical floating zone melting furnace and the effect of solidification rates on microstructures of the alloys was investigated.

TL;DR: In this paper, the T2 ternary phase is considered as the focal point of the microstructure designs, and the fundamental basis of the alloying behavior in T2 including the mutual solid solution with a wide range of transition metals has been established in terms of the governing geometric and electronic factors.

TL;DR: The tensile deformation mode at ambient temperature and the crevice corrosion resistance at a high temperature of 373 K were investigated in Ti-15Mo and Ti -15Mo-1Fe alloys as discussed by the authors.

TL;DR: In this paper, the critical cooling rate for glass formation was measured for an Fe-based easy glass forming alloy using a wedge casting technique combined with direct temperature measurements and finite element heat transfer analysis.
