No. According to Karl Marx socialism would just be (if necessary) an intermediate step between other systems and communism; for the purpose of developing the productive forces that would lead to a superabundance of goods and services.
The main differences between communism and socialism are: communism is stateless, while socialism is controlled by the state; and communism is oppression-free, while state oppression can exist in socialism.
All those countries around the world known as "Communists" actually never made the final step into Communism, and therefore got stuck in Socialism. Furthermore, most got stuck on the most tyrannical form of socialism: Stalinism or Neo-Stalinism; an oppressive system in which the state has total control over its citizens.
