/ Renewable energy - Study goal - Posco Asia Fellowship
My goal for continuing my study in Korea is to learn High Entropy Alloys (HEAs). "Everything is made of something," and we called that something is material. Every new material brings us to the new age of technology: stones ages, iron ages, bronze ages. From this, we can see the importance of the material in our history. The new era of technologies always starts with the new material that can sustain the technologies leap. More diverse research about materials is held to support the need for the latest technologies (e.g., metals, polymers, ceramics, liquid crystals, composites).
Interestingly, the new metal material called High Entropy Alloys (HEAs) emerges from material and science engineering research in 2004 by professor Jien-Wei Yeh. In the last few years, High Entropy Alloys (HEAs) have become one of the most popular research areas because the material shows an outstanding mechanical property for the future of material. However, there is not much research on this material in Indonesia because of many other reasons like technical difficulty, experience, and fundamentals understanding. In this case, Korea is one of the countries focusing on finding new material for the future with much more research and knowledge. I am interested in prof Hyoung Seop Kim from POSTECH (Pohang University of Science and Technology), Structural Nano Metals Processing Lab. Prof Hyoung Seop Kim is a pioneer researcher in High Entropy Alloys (HEAs). From the paper by prof Hyoung Seop Kim that I have been read. He is researching how to strengthing the High Entropy Alloys (HEAs) using severe plastic deformation, annealing, hot rolled, cold rolled, the addition of another element ( Co, Si, and V), and high-pressure torsion.
The research paper by prof Hyoung Seop Kim mostly tries strengthing the High Entropy Alloys (HEAs) from the inside by making the best grain possible. In this case, I propose strengthing the material from the outside. I am planning to fuse two materials by gluing the material together. This kind of approach, not something new, and this kind of material is called Fiber Metal Laminates (FMLs). This material uses aramid, carbon, and glass and combines them with metals in the hope of eliminating the weakness of both materials by completing each other. So I propose to use Carbon Fiber Reinforced Polymer (CFRPs) and High Entropy Alloys (HEAs) by directly bonding them using adhesive. I am not strange with this kind of approach because I have experience with Fiber Metal Laminates (FMLs). Fiber Metal Laminates (FMLs) is my topic in my undergraduate research, but I am using aluminum as the metal. By combining these two materials, I hope to get new material for the future to sustain our needs in many sectors.
I already fix it, and feedback will be appreciated.
