No. Although people scream when I say it around here, the Eucharist is Christ's sacramental presence, not physical presence (Real and True Presence, but sacramental, not physical) -- the physical accidents are those of wine and bread. Therefore, liturgical vessels aren't relics. Moreover, liturgical vessels are consecrated for use at the altar, and therefore, shouldn't be taken away for personal use (even if it's devotional use).
One has to be careful with words in this (because people tend to get shocked easily on this subject!)... the accidents remain, the substance is Christ.
Remember that the Church uses the word 'substance' in its philosophical meaning - i.e. "what stands beneath/behind" : one might also use the word "realisation" when it comes to the consecrated species where it is Christ that we realise that we are seeing, just like when we see flour, yeast, water etc mixed together and cooked that we realise that we are seeing bread, and not just the constituent parts. You might say that the priest 'cooks' the unleavened bread by means of consecration and the result, through transubstantiation - that is the transforming of the substance of the bread - is Christ.
Thinking then about the actual physical materials that come into contact with the transubstantiated bread and wine: well they should be worthy and held special and apart from profane usage. They aren't for decoration or for casual usage, since we don't regard Christ in casual terms. They wouldn't however become 'relics' as such... sacramentals maybe - in that they may be blessed for their special purpose, but not relics... after all, if in coming into contact with the consecrated species everything became a 'relic', then every Catholic in the world having made his or her First Communion would instantly become a 'relic' - and I don't think you'll have heard anyone describe anyone as such!
