Chemical Engineering Basics
Pick out the wrong statement.
- A. Cold cracking of a weld is due to the presence of hydrogen gas in the weld
- B. True stress is given by, σ = σE (1 + εE), where σE and εE are engineering stress and engineering strain respectively
- C. Phosphorous can be easily recovered in the iron blast furnace
- D. High residual stress at the surface is beneficial for fatigue properties of a material
