For anyone involved in the mechanical engineering, materials science, or manufacturing sectors, understanding the behavior and integrity of steel is paramount. The Udemy course, ‘Metallurgy: Mechanical Properties & Testing of Steel,’ offers a comprehensive journey into the heart of this crucial material. This course excels in breaking down complex metallurgical concepts into digestible modules, making it accessible even for those new to the field.
The course begins with the foundational elements of crystal lattices, explaining their structure, types, and the calculations associated with them, such as atom count per unit cell and atomic packing factor. It then delves into polyhedral voids within FCC and BCC structures, providing detailed calculations for octahedral and tetrahedral voids and their sizes, with a specific focus on their relationship with iron.
A significant portion of the course is dedicated to understanding the impact of carbon on steel’s properties. It covers the basics of carbon solubility, how it affects lattice structures, and the resulting changes in hardness. The concept of Carbon Equivalent is thoroughly explained, including its calculation and its vital role in understanding weldability. Furthermore, the course details Chromium and Nickel Equivalents and their relationship to weldability, offering practical insights for fabrication processes.
The latter half of the course shifts focus to the practical aspects of steel integrity through inspection and testing. It covers a wide array of testing methods, divided into four key sections: Metallurgical Testing, Destructive Testing, Non-Destructive Testing, and Visual & Marking Inspections. Under Metallurgical Testing, students will learn about Grain Size, Intergranular Corrosion (IGC), Ferrite content, Hydrogen-Induced Cracking (HIC), and Sulfide Stress Corrosion Cracking (SSC), with specific notes on Stainless Steel (SS) applications.
Destructive Testing methods like tensile, bend, flattening, impact, and creep tests are explained in detail. The Non-Destructive Testing section provides a thorough understanding of various techniques including Ultrasonic, Magnetic Particle, Radiographic, Liquid Penetrant, and Acoustic Emission testing, along with their purpose and definitions.
Finally, the Visual & Marking Inspections module covers essential practices like Hydro testing and Visual Inspection, crucial for quality control. The course emphasizes the continuous nature of pipe inspection and its importance in the process and piping industry, referencing key industry standards such as ASME, ASTM, and API.
What sets this course apart is its blend of theoretical depth and practical application. The instructors clearly explain the ‘why’ behind each concept, making the information stick. The lifetime access to course materials is a significant bonus, allowing learners to revisit topics as needed. Whether you are an entry-level technician looking to build a strong foundation or an experienced professional seeking to refresh your knowledge, this course is an invaluable resource. It equips students with the fundamental knowledge of inspection and testing requirements essential in the piping industry, making it a highly recommended investment for anyone serious about steel.
