Shear band and dynamic recovery of hexagonal close-packed materials.
Mg corrodes very quickly when in contact with water, therefore it requires special precautions during mechanical and electrolytic polishing. Mg is also a very soft, which makes it difficult to obtain a deformation-free surface using standard sample preparation techniques. An alternative technique is to use broad ion beam milling, such as Fischione Instruments’ Model 1061 SEM Mill or Model 1062 TrionMill, both of which can achieve a high-quality polished surface on sensitive materials without the use of chemicals.

Fischione Model 1061 SEM Mill (Ion Milling)
-
Minimal maintenance -
Due to the efficiency of ionization, maintenance of the TrueFocus ion source is minimal and the components have an extremely long life. Material sputtered from the ion source is negligible, minimizing both sample contamination and component maintenance. Automated shuttering prevents the buildup of sputtered material on the viewing window. All system components are easily accessible for routine cleaning. - Programmable - Sample rotation is 360° with variable rotation speed and a sample rocking feature. The instrument automatically senses the sample thickness and establishes the milling plane, which maximizes throughput. A magnetic encoder provides absolute positioning accuracy.
- Automatic termination - The ion milling process can be automatically terminated by elapsed time or by temperature.
- Time - A timer allows milling to continue for a predetermined time and then turns off the energy to the ion sources when the time has elapsed. The sample remains under vacuum until the load lock is vented.
- Temperature - The thermal safeguard associated with the sample cooling system will stop the process if the sample stage reaches a preset temperature.

Fischione Model 1062 TrionMill
Fischione Instruments’ Model 1062 TrionMill is an excellent tool for creating the sample surface characteristics needed for SEM imaging and analyses. The TrionMill’s three ion sources provide large-scale milling of planar and cross-section samples. High-energy operation allows rapid milling of large areas (up to 50 mm); low-energy operation allows gentle sample polishing.
- Three independently adjustable TrueFocus ion sources
- Planar sample sizes up to 50 mm diameter by 25 mm height
- Controllable beam diameter over a wide range of operating energies (100 eV to 10 keV)
- Liquid nitrogen-cooled sample stage (optional)
- Vacuum/inert gas/cryogenic transfer system protects environmentally sensitive samples (optional)
- Remote operation
