I mixed tungsten and titanium and sintered it in cylinder shape diameter 50mm with thickness 4mm. I would like to observe the fracture morphology under SEM. But to study the fracture morphology first I need to break it. WTi is very hard material. I unable to do tensile or compression test to break as the sample is too small. Is there any way to break it like using chemical or how? In published paper they do not mentioned in details how they break it.

Thank you in advance,
