Metals with wide stacking faults (low SFE) strain-harden more rapidly, twin easily on annealing, and shows a different temperature dependence of flow stress than metals with narrow stacking faults.

The _______ the stacking-fault energy, the higher the separation between the partial dislocations and the ________ the stacking fault.

Which of the following represents the extrinsic stacking fault in the FCC Metal?

The stacking fault in FCC will create a thin region of ___________ in stacking of the FCC.

The stacking sequence of the atomic arrangement for HCP is ___________

The stacking sequence of the atomic arrangement for FCC is ___________

Which of the following is not matching correctly?Metal ————> Twin Plane ———> Twin Direction

There are three metals given below.Metal A – Very few numbers of the slip systemsMetal B – High critical resolved shear stressMetal C – High number of the slip systemWhich of the following is more susceptible for twining?

Twinning is not associated with specific crystallographic direction; it only depends on the direction of mechanical force. There is no preferred orientation of twinning in crystal.
