Two-wavelength holographic measurement of temperature and concentration during alloy solidification

摘要: Introduction I techniques are helpful tools for fundamental investigations of the fluid flow, temperature, and concentration distribution in front a solidifying interface. These effects change solidification conditions cast metallic materials; hence, they influence their microstructure. In order to optimize properties castings, comprehensive knowledge is required interaction between flow melt temperatureand concentration-dependent layers close front. Transparent model systems that solidify same manner as metals can be effectively utilized because allow situ observation interferometric measurement environment solid/liquid interface." The objective this work describe new method simultaneous measurements temperature different g environments adjacent interface alloys using transparent monotectic systems. "two-wavelength holographic" provides opportunity direct concentration.
