How to define a grain in relation to metallurgy? Is it a right to say :a grain consists of crystals oriented in a particular direction ?
grain = one crystal !!! Orientation of grains may be same or may not be same. But two different orientation leads to mismatch resulting in high energy state called grain boundary.
hope it fine
But still the grain is not defined,,,you defined the grain Srivatsa
Dear Colleagues,
Thank you so much in advance. I think that, we can define a grain as single crystal with highly condensed element within its boundary, or it is a small container of one chemical element! for example in Ferite, the grain is a condense of Carbon element with specified boundary. For more detail, please see the famous engineering book ASHBY, you will rich information. See the attachment, please give me feedback.

Grain is a container of atoms arranged in a particular orientation.
