6:18 U mention steel & cast iron compositions without mentioning the temperatures, does it mean less than 2% C by weight is steel for the entire range of temperatures and likewise between 2 & 6.7% is CI for the entire range of temperatures? Thank u
How should a mechanical engineer use this knowledge of Iron carbon equilibrium diagrams on his job in the selection of carbon steel and alloy steel and welding of carbon steel and alloy steel pipes And tubes under different operating conditions. Operating conditions may include corrosive applications, high pressure or high temperature applications.
Knowledge of iron-carbon equilibrium diagrams plays a crucial role in guiding mechanical engineers when selecting carbon and alloy steels for various applications. By understanding phase transformations depicted in these diagrams, engineers can choose steel compositions that align with desired mechanical properties, such as strength, toughness, and corrosion resistance. Engineers optimize heat treatment cycles to strike a balance between strength and toughness, especially in high-pressure environments where mechanical integrity is paramount. Welding procedures are also influenced by phase diagrams, with parameters adjusted to minimize the formation of undesirable phases in the heat-affected zone. Preheating and post-weld heat treatment procedures are designed to prevent brittle phase formation and ensure the integrity of welded joints. Moreover, the selection of corrosion-resistant alloys is informed by phase stability diagrams, enabling engineers to choose materials suitable for corrosive environments. Surface treatments such as pickling and passivation are chosen based on steel composition and phase stability to enhance corrosion resistance further. Ultimately, a comprehensive understanding of iron-carbon equilibrium diagrams empowers mechanical engineers to make informed decisions regarding material selection, heat treatment, welding, and corrosion protection for pipes and tubes across diverse operating conditions.
@@ProfDrVasimAShaikh Extremely grateful for this masterpiece information. Worthy of saving for reference. It’s so informative. I believe this is the first lesson metallurgy professors should teach or educate & indoctrinate their students for motivation before continuing with metallurgy lectures & lab. Metallurgy is extremely valuable important subject for ME hired as process mechanical engineers in a petrochemical refinery & chemical industry in general to hand out welding procedures for different process requirements and selection of steel grades to meet various process requirements, avoid failures & shutdowns or downtimes. Best wishes to u Dear Professor You have a great attitude 👍
Key temperatures, composition, Reactions
1148C 4.3% Eutectic L to γ + Fe3C
1493C 0.18% Peritectic δ+L to γ
727C 0.76%. Eutectoid γ to α +Fe3C
Correct.
Killer explanation! Thanks!
Thanks for watching.

👍
explanation would be more better than this, little complex
Ok. I will try to simplify even further.
Nice ❤❤❤
Thanks 🤗
