Jad Houssein develops an innovative method to measure the thermal diffusivity of liquid metals at high temperatures

Jad Houssein, from the National Polytechnic Institute of Brittany, has developed a method to measure the thermal diffusivity of liquid metals at temperatures exceeding 1,500°C. This advancement addresses a crucial need in the metallurgical industry, where accurate data could optimize the production of 10.7 million tons of cast parts in Europe, representing a market of 50 billion dollars in the United States.

Thermal diffusivity is essential for the performance of metals in high-temperature environments. Jad Houssein's thesis addresses the measurement of this parameter for liquid metals, a major issue for the metallurgical industry. The lack of reliable data has long hindered innovation, as traditional methods are unsuitable for the extreme handling conditions.

Houssein has developed an innovative method that allows for the measurement of thermal diffusivity without physical contact, suitable for extreme temperatures. This approach could transform manufacturing processes, ensuring higher quality cast parts and reducing defects. Preliminary results show a significant improvement in measurement accuracy compared to existing techniques.

The implications of this research are strategic for the metallurgical industry. By optimizing manufacturing processes through accurate data, companies can reduce costs and improve the quality of their products. Decision-makers should view this advancement as an investment opportunity in technologies that meet the growing demand for high-performance materials.
