The grain boundary is made of a regular array of edge dislocation at define spacing. In the case of low angle grain boundary, the distance between dislocation array will be small, and for high angle grain boundaries, it will be large.

The grain boundary is made of a regular array of edge dislocation at define spacing. In the case of low angle grain boundary, the distance between dislocation array will be small, and for high angle grain boundaries, it will be large. Correct Answer False

In the case of low angle grain boundary, the distance between the dislocation array will be large because, to accommodate the mismatch, small number of dislocations are required. For the high angle grain boundary, it will be necessary be a large number of dislocations, so interspacing will be low.

Mohan traveled five cities (A, B, C, D and E) starting from home by a car which has a mileage such that the car can travel 10 km in 1 liter petrol. Distance between city A and B is twice the distance between home to city A. Distance between city B and C is thrice the distance between home to city A. Distance between city C and D is 100. Distance between city D and E is 1.5 times than the distance between B and C. Average distance traveled by Mohan was 41 km between five cities. Find how much petrol was needed by Mohan to travel from city B to D.
