Cannot be formed below 1 200°c
Webstructures on LN cannot be formed below 300°C, and the di-rection of formed ripples is parallel to the laser polarization direction. However, when the temperature is raised to 300°C, the periodic surface structures change into comparatively uniform ripples, and their direction is perpendicular to the laser polarization direction. WebThe eutectic between aluminium and Al 6 Mn is 1.3% manganese and 660 °C, while pure aluminium melts at 660.2 °C. Values of 1.8% and 657 °C or 658 °C can also be found in older literature. Above 710 °C, Al 4 Mn is formed with a manganese content of at least 4%. However, such high levels are not technically used. Below 510 or 511 °C, Al 12 ...
