Which risk increases when forging iron suspension bridge eyebars below the critical temperature?

A)Weld decay propagates faster
B)Grain boundary slip worsens
C)Strain hardening accelerates failure
D)Tempering embrittlement process intensifies

💡 Explanation

Strain hardening failure risk does increase because, at lower than recommended temperatures, the mechanism of work hardening increases the material's brittleness and yield strength, resulting in material failure; therefore, this is more likely, rather than faster creep due to grain boundary issues that appear at higher temperature conditions.
