Temperature-induced processes for size-selected metallic nanoparticles on surfaces

•FeNi nanoparticles on W(110) are stable at room temperature and above.•Unrolling carpet mechanism is driving the melting of nanoparticles.•Ostwald ripening is driving the formation of FeNi islands after melting. The melting behavior of Iron-Nickel alloy nanoparticles on W(110) was studied under UHV...
