Purpose: The article describes a new developed method for producing fine-grained materials, such as DRECE (DRECE, Dual Rolling Equal Channel Extrusion). Design/methodology/approach: The process of forming of material using the DRECE technique is based on making use of the material’s intensive plastic deformation, i.e. that process is a combination of two known technologies, ECAP and CONFORM. Findings: The article presents the results of both exams, including photographs of cracks. Mechanical properties of the steel grade11 321 before and after extrusion by DRECE tool are described as well. Research limitations/implications: The article describes the process of forming of metal sheets made of steel grade 11 321. It further describes two methods for detection of deep drawing - Erichsen and Fukui. Originality/value: The article describes the process of forming of metal sheets made of steel grade11 321. It further describes two methods for detection of deep drawing - Erichsen and Fukui. These methods were applied to the extruded metal sheet by DRECE tools.
