In the past, strength properties of structural materials have been evaluated by destructive testing, however it was difficult to obtain and evaluate exhaustive data when the number of destructive tests increased, which was costly and time-consuming. Mitsubishi Heavy Industries, Ltd. (MHI) has established a technology to promptly predict material strength properties by applying informatic science, known as materials informatics, to structural metal materials. This technology is expected to contribute to the reduction of material strength variation, improvement of manufacturing yield, and advancement of life evaluation technology. This report describes case studies of applying the established technology to long steam turbine blades and high-temperature steam piping of thermal power plant.
