TLDR
In this article, the changes in the morphology of lath martensite with hot-deformation of austenite were studied by using an 18Ni maraging steel and the relationship between packet size (or block width) of martensites and the grain size of the prior austenites was discussed in detail.About:

Influence of Ultrafast Cooling on Microstructure and Mechanical Properties of Steel
TL;DR: In this paper, the effect of ultrafast cooling on microstructure and mechanical properties of steel with different carbon composition has been investigated and it has been observed that the steel with higher carbon content requires higher water flow rates to reach an ultra fast cooling rate of more than 140°C−1.

Surface modification of nano‐sized silicon nitride with BA‐MAA‐AN tercopolymer
TL;DR: In this article, a macromolecular coupling agent (BA-MAA-AN tercopolymer) was used for surface modification of native nano-sized silicon nitride (Si3N4) powder.

Nano-composite martensitic steels
TL;DR: In this article, the authors have disclosed that carbon steels of high performance contain dislocated lath structures in which laths of martensite alternate with thin films of austenite.

Microstructural changes produced by hot forging in a C300 Maraging Steel
TL;DR: In this paper, the microstructural changes induced by hot forging in a maraging C300 steel were analyzed and it was shown that an important refinement of the martensite block width was obtained when hot working produced either work-hardened or partially recrystallized austenite.

Thermomechanical treatment of a low carbon CrNiMo steel
G Venkataraman,A.K. Mallik +1 more
TL;DR: In this article, the influence of thermomechanical treatments (TMT) has been studied in a low carbon CrNi-Mo steel with equal amounts of total deformation of austenite, LTMT, i.e. low temperature (550°C) TMT and HTMT, produced nearly equal martensite lath size.

Thermo-mechanical treatment of steel
TL;DR: In this paper, a hypoeutectoid steel is heated to the AC3 point +100 deg.C and hot worked at >=20% working rate and a working finish temp which is below the heating temp. by approximately 50% of the heating temperature.
