The favorable and unfavorable effects of oxide and intermetallic phases in conductive materials using laser micro technologies

In laser technological processes, which are connected with phase transitions, special changes in material structure occur. These changes of structure include among others phase composition as well as morphology. The changed structure determines the electrical, mechanical and functional properties of the material. The problems become of greater importance in laser microtechnologies when areas with changed structure have dimensions measurable in micrometers, and volume of an order of 10−3 mm3. The favorable and unfavorable effects of the structural changes of materials and functional properties of elements produced by means of laser microtechnology have been analyzed in the paper.
