Proof of micromanipulation at high temperatures: Fig. 2 shows aluminium alloy in the semi-solid range at 623ºC after movement of the probe tip. Fig. 3 shows enhanced sintering of copper particles under force from the micromanipulator .
Probe tip (can be slimmed as research continues)

Fig. 3 a) Copper particles A and B under force (the arrows show particles which disappear later in sintering)
Fig. 3 b) Close-up showing neck formation at 301oC (a temperature well below the temperature it would occur without force).
