Design of Advanced Alloys for Naval Engineering Applications¶
Dr. Wei Xiong Discusses the Project Supported by Office of Naval Research¶
"There are several metals, from nickel alloys to aluminum and titanium, which are the foundation for AM production of complex parts with properties that could not be developed via traditional, or subtractive, manufacturing. However, many of these materials are not at strong or reliable in the harsh environment of the sea, and that's a disadvantage for the Navy and other maritime agencies," Dr. Xiong said. "Steel is still the best, most versatile and structurally sound metals for naval construction and repair, and so our research will focus on developing new toolkits to leverage the use of new steel prototypes in AM that will benefit the U.S. Navy."
New York Times Discussing Tesla Cybertruck and Dr. Xiong's View about Alloy Design¶
This example demonstrates the critical role of materials design and ICME (Integrated Computational Materials Engineering), a field often overlooked by the public. Experts like Dr. Wei Xiong have long understood that methods such as CALPHAD-based ICME are now essential for designing advanced alloys and optimizing the processing of traditional ones. A prime example is the use of 316L stainless steel for Cybertruck manufacturing. This interview occurred when Elon Musk announced the Cybertruck idea, and many people still had questions about the possibility of using stainless steel for such a large vehicle. The journalist was convinced to some extent, and added "Maybe" to the title of the news article.
