I am taking welding metallurgy class and I have a Abstract project that I have to do and need help with suggestion on topic to talk about. Here is the requirement of the abstract I have to do.

Introduction (100 words)-Describe the subject of the poster, problem/issue being addressed and it's practical implications for the welding industry.

Technical Approach & Results (200 words)- Explain the technical approach. Summarize the work that was done as it relates to the subject of the poster.

Conclusions (100 words)-Summarize the conclusions and how they could be used in a welding application.

I was told that I can chose a number of things to talk about...such as weld defects,phase diagrams or anything that relates to welding or metallurgy would be ideal discussion.

Any helpful suggestions and help would be appreciated.
