Abstract. Grain boundary sliding, a deformation mechanism of superplasticity, occurs only at high temperatures, making it difficult for superplastic steels to be practically applied due energy consumption and surface oxidation. Therefore, in the present study, we introduce newly developed Si-added medium-Mn steel, which can superplastically deformed such low temperature 763 K. The low-temperatu...

Design optimization of product with the objective reducing weight is one current focuses in a design. In vehicle industry, particular, reduction has significant impact on efficiency improvement and fuel economy. These improvements can have direct operating costs vehicle. The methods used to are by optimizing product́s parameters replacing conventional materials highly sustainable strengths. this...
