(1) is the movement of atoms, ions and other species through a material. There are two driving
factors responsible for this phenomenon. These factors include _(2)_ and _(3)_. In Materials we
are primarily concerned with interdiffusion as opposed to self diffusion as this is the mechanism
that is involved in a variety of material processes such as carburizing and nitriding. There are
two mechanisms for interdiffusion these include (4) which is the movement of atoms from one
vacancy site to another and (5) which is the movement of atoms from one interstitial site to
another The _(6)__ mechanism results in a faster rate of diffusion than the (7)_ mechanism
because there are more _(8)_ sites and because this mechanism also has a lower (9) energy.
There are three types of diffusion and these include _.(10)_ , __(11)___ and ___(12)_. The
slowest type is _(13)_ and the fastest type is _(14)_. We can use _(15)_ to predict the rate of
diffusion. Diffusion will occur faster in crystal structures that have lower (16) such as BCC as
opposed to those that have higher _(17)_ such as HCP. Diffusion is also affected by_(18)_ and
_(19)_. _(20)_ which is when a material subjected to a constant stress that is below its yield
stress at elevated temperatures will plastically deformed is a diffusion controlled property.
