The goal of this thesis is to design a furnace to be used in in-situ time-resolved x-ray scattering studies of processes such as crystallization in 25 mum thick metallic ribbons. Two approaches are tested thoroughly. The first is to use forced convection to heat the sample. This is tested experimentally up to about 500 K with 1.5 mm thick samples and theoretical calculations are used to resolve these data and to predict the behaviour of the thin ribbons at higher temperatures. The results show that the ideal configuration for this heating mechanism involves heating the ends of the samples while allowing hot gas to flow over the surface. Despite its expected advantages, such as small thermal gradients within the sample, this system should have poor long term stability and require a difficult calibration in order to couple the gas heater to the heaters at the ends of the sample.
