摘要：

The structure of copper-aluminum system polymetallic samples obtained at significant variations of manufacturing mode parameters from optimal values has been studied. It is revealed that at formation of samples by means of wire additive electron-beam technology there is a formation of several basic kinds of defects of various structural scale levels. In the structure at underheating of copper wire there is a formation of a large number of pores and unmelted particles of wire. The most significant defects are formed at the combined effect of non-melting wire and positioning inaccuracies.
