TL;DR: In this article, the deformation behavior of ultrafine/nanograined (UFG/NG) structures during tensile straining has been examined by electron microscopy in metastable austenitic steels.

TL;DR: In this paper, annealed steel plate has been unidirectionally cold rolled up to 90% reductions under two different rolling conditions and the effect of rolling conditions on transformation of austenite to strain-induced α′ martensite phase and evolution of texture in both the phases have been studied as a function of rolling reduction.

TL;DR: In this paper, the percentage of coincident site lattice boundaries did not correlate well with the degree of sensitization, while specimens with larger grains showed an increase in sensitivity with sensitization time.

TL;DR: In this article, the evolution of texture in metastable austenitic stainless steels under subzero rolling and cold rolling conditions was studied, and the magnitude of strain-induced α-martensite phase formed under sub-zero and subsequent cold rolling condition was found to be larger than only cold rolling under same amount of deformation.

TL;DR: In this paper, a powder metallurgical route has been investigated using pressureless sintering and hot pressing techniques to fabricate Al-TiN (10, 30 wt.%) composites, and the presence of titanium nitride (TiN) particles at grain boundaries played a significant role in improving the densification and results in improved mechanical properties.
