Hi everyone! I’m analyzing the microstructure of the coarse-grained heat-affected zone (CGHAZ) of welded EH36 steel, and I’d love to hear your expert opinions. Based on the literature and my observations, I’ve tentatively identified the phases marked in the image as follows: 1️⃣ Grain Boundary Ferrite (GBF) – Ferrite blocks along the prior austenite grain boundaries. 2️⃣ Widmanstätten Ferrite – Plate-like or acicular ferrite within the grains, typical of rapid cooling in CGHAZ. 3️⃣ Bainite – Lath-like regions formed at intermediate cooling rates. 4️⃣ Martensite-Austenite (M-A) Constituents – regions, often near grain boundaries or within grains, associated with hard, brittle phases. These are my interpretations based on the literature and microstructural features. 🔍 What do you think? Do you agree with these phase identifications? Are there other potential phases or features that I might have overlooked? Any insights or experiences you’ve had with CGHAZ in EH36 steel? I look forward to learning from your expertise! Please share your thoughts in the comments. Feel free to share similar observations or references for further reading. Your input will be greatly appreciated! Thank you in advance! 😊
