Some thin-film specimens for TEM analysis should be prepared at low temperatures. For instance,  Al2CuLi TEM specimens had been prepared by electrodischarge-machining 3 mm diameter rods from the alloys, and slicing disks from these rods for thinning. Thin-film TEM specimens were then produced by ion-beam milling with the specimens cooled to liquid nitrogen temperature [1].
