Answer Source
From the MSDN page for create default:
Any constant, built-in function, or mathematical expression can be used, except those that contain alias data types. User-defined functions cannot be used
Like M.Ali writes, you can use a user-defined function if you create a column-bound default constraint with alter table ... add constraint or create table ... (col1 default dbo.MyFunc());.
