Mechanical properties and microstructures of China low activation martensitic steel compared with JLF-1
117
TL;DR: The tensile and impact properties of CLAM steel are compared to those of JLF-1 steel in this paper, which shows that the finer grain and lath structure is one of the main reasons for the higher strength and lower ductile-to-brittle transition temperature (DBTT).

High strength-superplasticity combination of ultrafine-grained ferritic steel: The significant role of nanoscale carbides
TL;DR: In this article, the authors describe the mechanistic basis of obtaining high strength-high plasticity combination in an ultrafine-grained (UFG) (∼500 ± 30 nm) ferritic steel with nano-size carbides, which sustained large plastic deformation, exceeding 100 % elongation at a temperature significantly below the absolute melting point (Tm).

The influence of the lath morphology on the yield stress and transition temperature of martensitic- bainitic steels
TL;DR: In this paper, a detailed analysis of lath orientations inside a packet is presented, which reveals that all laths in any one packet are similarly oriented and that in fact a packet contains many high angle lath boundaries which are given by laths adopting different Kurjumov-Sachs orientation variants during the γ → α transformation.
