Steel is the most common and the most important structural material. In order to properly select and apply this basic engineering material, it is necessary to have a fundamental understanding of the structure of steel and how it can be modified to suit its application. The course is designed as a basic introduction to the fundamentals of steel heat treatment and metallurgical processing.

This course focuses on the practical materials and processing knowledge necessary to perform failure analysis on these widely used component groups. The course materials and instruction will provide insight into the manufacturing of components, circumstances resulting in degradation, and diagnostic features for failure analysis and prevention.

Welding is the joining of two or more pieces of metal by applying heat and/or pressure to produce a localized union through fusion (melting) or diffusion across the interface that forms the joint.

­In this self-guided digital course, students will learn – with the help of rich visuals, narrated animations, and interactive quizzes – the different case hardening processes including carburizing, carbonitriding, and nitriding; quenching of case hardened parts; induction hardening; and the various types of furnaces used in commercial heat treating processes.

Corrosion occurs in all industries from automotive and aerospace to infrastructure, construction, petroleum, power, paper making, food processing, bioengineering, and pharmaceuticals. Where a corrosion failure has occurred, economical and practicable measures for prevention of future failures of the same type are required.

Corrosion testing and monitoring are powerful tools in the fight to control corrosion. Testing provides the necessary data for the evaluation and/ or selection of existing, alternative, or new materials in various environments. Monitoring allows workers to follow the effectiveness of a corrosion-control system and provides early warning when damaging conditions arise.

This self-guided digital short course uses helpful visuals, narrated animations, and interactive quizzes to teach fatigue failure, fracture due to cyclic stresses or strains below the tensile strength. Fatigue is among the most common causes of failure. Fatigue failure occurs because loading conditions are too severe, the component geometry is inappropriate, or the material or material condition is inappropriate.

In this self-guided digital course, you will learn the various heat treatment processes involved in modulation properties of steel, effect of carbon on the phases of iron and how it affects the microstructure, classification of steel and tempering of steel.

Selecting a material is one of the most critical design decisions an engineer can make. With the advent of new age materials and evolving technology in manufacturing processes, there is a tremendous opportunity for innovation in design by utilizing the materials in products that provide greater performance at lower cost. Compromises and trade-offs among various design variables are routinely made and factors that are important in one system may be insignificant in another. In this self-guided digital course, students will learn – with the help of rich visuals, narrated animations, demonstration videos, and interactive quizzes – how to evaluate the various factors that impact material selection for component design.

In this innovative self-guided digital course, students will learn – with the help of rich visuals, narrated animations, demonstration videos, and interactive quizzes – how to measure properties such as tensile strength, hardness, and impact resistance and what the tests reveal about material behavior and failure mechanisms, including fracture, creep, and fatigue.
