Evaluate, using an accredited data source, the microstructures outlined in Task 1 b) and Task 2
b) to identify the material, including how the history, impurities, and grain boundaries affect
the mechanical properties of the materials.

Introduction to the assignment In this assignment, I must take notes and gather information about the
grain structure's cross section. I need to do a lot of research to find the right information to complete
this assignment's requirements. I'm also going to watch useful videos to help me understa...

Steel Structure Steel microstructure is the fine structure of its constituents seen under magnification
over 25 times. It is determined by the carbon content and the transformations that occur during the
steel-forming process. Furthermore, it has a significant impact on the mechanical properti...

Task 2 b) (P2) The microstructures shown are from processed materials. Copy these figures (Figures 4,
5 and 6) into your assessment report, and make notes about the microstructure of each, giving your
explanation for each microstructure, and how this microstructure would affect the mechani...

Figure 6 This steel was subjected to a process known as carburization after it was initially cast. In a
carbon atmosphere, the metal is heated above the ferrite-austenite transition. This creates a
concentration gradient, allowing carbon to diffuse into the steel. Typically, the steel is hard...
