Would you mind explaining this a little more?saptmThat's the reason we are using drifts or a bigger pattern or mould for casting to avoid these types of problems.

Yes that is correct. But can we deal with atomic structures a bit. I am curious too 😀saptmya sure dude [😀]
we already knows that after solidification,the cast contracted.And since,we usually use sand dust for a mold or pattern due to which there come some roughness in the cast. So that's why we make the pattern bigger than the actual size of the cast so that we just get rid of all these allowance/defects.

What types of atomic structure you are taking about,i mean FCC,BCC HCP or SCC?IssueYes that is correct. But can we deal with atomic structures a bit. I am curious too 😀

I am talking about the grain structures. You see, as a casting is cooled, it shrinks. It is more of a function of its grain structure. Can you explain about it more? 😀saptmWhat types of atomic structure you are taking about,i mean FCC,BCC HCP or SCC?

I am not certain of what you are seeking but basic cooling of iron goes like this:IssueI am talking about the grain structures. You see, as a casting is cooled, it shrinks. It is more of a function of its grain structure. Can you explain about it more? 😀
