List at least two factors that promote transition from ductile to brittle fracture.

1 Answer

Answer :

Manner of loading, and the rate of loading promote transition from ductile to brittle frac¬ture. A
machine member may have ductile failure under static loading but may fail in brittle fashion when the
load is fluctuating. Similarly a material may evidence ductile failure under tensile loading at ordinary
testing speed but if load is applied at a high velocity then failure may be brittle.
