2D quantitative analysis of metal foaming kinetics by hot-stage microscopy
Abstract
Hot-stage microscopy (HSM) coupled with the free image analysis software ImageJ as an alternative and simple approach for quantifying the foaming kinetics of metallic precursors was studied. Rectangular extruded profiles of foamable precursor materials of aluminum alloys, AA 6061 and AlSi7, of 160 × 20mm2 and 20 × 5mm2 cross-sections, respectively, were used in this study. These profiles were prepared in a three-step process, comprising powder mixture, cold isostatic pressing and hot extrusion. The foaming experiments were performed at a constant heating rate of 10°C min-1 using a hot-stage microscope equipped with an alumina furnace. The temperature was measured using a thermocouple inside an alumina pyrometric bar on which the holder with the sample is placed. The HSM results indicate that 1 s time step enables the detailed observation of phenomena occurring at the outer surface of the sample. The most important stages of foam evolution can be identified, starting from the unfoamed sample.
