It is indicated that LiZn behaves as acceptor in the material.
As a result, in Li-doped ZnO, Lii is always in the material to compensate the acceptor which LiZn always behaves as.

Increasing the Quality of Welded Joints of Al-Si 6082 Alloys by Introducing Forced Vibrations BODEANU Mihai Alexandru1,a* and MACHEDON PISU Teodor1,b 1Transilvania University of Brasov, Faculty of Materials Science and Engineering, Materials Engineering and Welding Department, 29 Eroilor Blvd., 500036, Brasov, Romania abodeanum88@yahoo.com, btmache@unitbv.ro Keywords: forced vibrations, aluminum alloys, welding technology Abstract.
There are many papers that highlight the positive role of vibrations in materials solidification and welding, refining the structure, increasing the mechanical properties and decreasing the internal stresses [2, 3].
Materials and Methods To perform the experimental tests were used samples of aluminum alloy 6082 (AlSi1MgMn) and as filler Al 4043 (AlSi5) alloy wire.
Vickers HV0.1 micro-hardness in the weld and in the thermal influenced area Al 6082 Alloy Micro-Macro Structure For microstructure analysis of the welded alloy was used the OMNIMET- BUEHLER equipped with a microscope whose resolution goes up to 1000x and one analysis program for ferrous and nonferrous materials.
