abstract

  • A new method of developing lean powder metallurgy steel is proposed. The microstructure of the steel is tailored by combining two different prealloyed steel grades. These materials open a new niche in steel grades for high-performance applications by using a low-cost method of production. Moreover, an alternative route to developing microstructures suitable for manufacturing TRIP and/or Q&P steels is proposed avoiding some of the complex steps that must otherwise be taken to obtain the proper starting microstructure.
