"Assessment of microstructural characterization and Thermo-Kinetic simulations for producing strengthened and toughened martensitic steels";
Materials Today: Proceedings, 44 (2021), 6; 4903 - 4907.

Martensitic steels possess higher strength and toughness as the carbon content is minimum and
strengthened by precipitation hardening. Hence various factors such as chemical composition, production
techniques, heat treatments influencing the properties of martensitic steel were chosen for review.
An attempt has been made to understand various available microstructural characterization techniques
with their unique features and also predictions as made with the help of thermo-kinetic simulations for
microstructure evolution. It is witnessed that vacuum induction melting is preferred for steels to achieve
the highest purity. For understanding the evolution of microstructures during heat treatments, studying
precipitation kinetics through micrographs has emerged very important for identifying strengthening
mechanisms. Professional software can be used for prediction purposes, which also saves a lot of time,
effort, and cost. Including Atomic Probe Tomography for microstructural characterization, helps in identifying
nano-sized coprecipitation mechanisms.

1. Introduction
Despite the development of several alloys and various composite
materials, Steel because of its availability in various grades,
durability, and formability, is the most preferred engineering
material. Steel melting by conventional and additive manufacturing
techniques can bring a lot of difference in the final properties
of the alloy. Chemical composition and heat treatments are key
for microstructure evolution. A detailed discussion is presented
by categorizing the literature on, various melting techniques with
their specific applications, heat treatments carried for different
compositions of steel, and predictions made by thermo-kinetic
simulations using professional software. Microstructure characterization
is key in identifying strengthening and toughening mechanisms,
advancements made in this regard has been deliberated in
detail as
