Knowing how strong a piece of steel is, especially the stainless steel used in everything from cars to buildings, is vitally important for the people who make and use it. This information helps to keep people safe during crashes and to prevent buildings from collapsing.
Accurately predicting the strength of a steel prototype based on its microstructure and composition would be indispensable when designing new types of steel, but it has been nearly impossible to achieve — until now.
“Designing/making the best-strength steel is the hardest task,” said Dr Harishchandra Singh, an adjunct professor at NANOMO and the Centre for Advanced Steels Research at the University of Oulu in Finland.
Estimating the contribution of various factors towards designing high-strength novel steel has traditionally required numerous tests that can take months, according to Singh. Each test also requires a new sample of the prototype.
