A voyage back as result of making a name for oneself (5)
I believe the answer is:
alias
'result of making a name for oneself' is the definition.
'a voyage back' is the wordplay.
'voyage' becomes 'sail' (sail is a kind of voyage).
'back' shows that the letters should be reversed in order.
'sail' reversed gives 'lias'.
'a'+'lias'='ALIAS'
'as' is the link.
(Other definitions for alias that I've seen before include "Otherwise - an assumed name" , "aka" , "another name" , "one's assumed" , "Otherwise known as" .)
