Beschreibungen/Notizen

• The research deals with the modification of AlSi 5 Cu 2 and AlSi 10 Cu 2 alloy surfaces by the method of electron beam processing. It is established that the irradiation of the alloys by concentrated energy flow is accompanied by the increase in microhardness and covering the surface defects. Due to a great temperature difference between two media the surface melts at a superhigh rate and crystallizes again, because of it a grain size decreases resulting in the increase in microhardness. The arising tensile stresses contribute to the covering of the surface defects.
