Steel, ever-evolving material, has been the most preeminent of all materials since it can provide wide range of properties that can meet ever-changing requirements. In this course, we explore both fundamental and technical issues related to steels, including iron and steelmaking, microstructure and phase transformation, and their properties and applications.

Microstructure and phase transformation in steels I: Fundamentals
In the following 3 courses, microstructure and phase transformation in steels will be discussed in detail with specific examples. This course in particular, covers the basic terminology, general explanation on iron-carbon system and concepts you must know to understand the phase transformation of steels.
Microstructure and phase transformation in steels II: Non-equilibirum microstructure in steel
This course explains the non-equilibrium microstructure, and related displacive transformation in steels. Phenomenological theory on martensite transformation will be introduced, and other concepts such as Ms temperature and bainite microstructure will be covered as well.

Microstructure and phase transformation in steels III: Role of alloying elements in steels
Material design based on alloying is covered in this course. Role of alloying elements in steels with respect to the control of microstructure and mechanical properties will be discussed in detail. Influence of alloying elements on phase stability, transformation kinetics, and strengthening of steels is discussed.
In the following 3 courses, different types of steels will be introduced with their properties and applications. This course typically covers some of the first generation steels containing conventional low strength steels and HSLA (high strength low alloy) steels. Detailed explanation on the microstructures and related properties will be treated.
Characteristics of acicular ferrite, micro-alloyed carbon steels, and multiphase steels will be discussed with information on their production and applications. Martensitic steels and effect of various heat treatments will also be discussed.

Fantastic overview of the properties of ferrous alloys. It would be a bit challenging if it was your first introduction to the coursework, but as a review it is superb.
POSTECH opened its doors in 1986 as the first research-oriented university in Korea to educate the brightest minds in the country and lead the transition of Korea’s higher education from dissemination to creation of knowledge. Since its establishment 30 years ago, POSTECH has taken on numerous challenges and innovations to revolutionize the culture of and raise the bar for scientific research in Korea. As such, the past three decades represent the proud history of POSTECH, which has marked a meaningful milestone in the community of higher education and science/engineering in Korea and has since grown into one of the top universities in Asia.
Now, POSTECH is poised to take another leap forward over the next three decades: driven by the open and fearless spirit to tackle the unknown, it will serve as a flagship university that proposes a new role for value creation in society. We at POSTECH will continue to dedicate ourselves to our mission—providing the finest education and fostering talented youth into leaders equipped with a comprehensive and essential skill set for the future. Also, we will further build upon the research excellence POSTECH has achieved thus far to make direct contributions not only in expanding boundaries of scientific knowledge but also in leading the socio-economic progress of the country and region.
The founding tenets of POSTECH aims to serve the nation and humanity through education, research, and industry-academic cooperation. Going forward, we will spare no efforts to open a new path of value creation through continuously ensuring “devoted education,” “outstanding research,” and “robust job and business creation” and to develop into a top global university that proudly represents Korea....
