“Influence of parameters of hydrostatic extrusion plastic processing technology on properties of metals and metal alloys for industrial applications”.
Previously conducted research was mainly focused on the influence of extreme plastic deformations obtained by hydrostatic extrusion (hydroextrusion) on the properties of materials, mostly without considering the possibility of their practical application. The research carried out within the presented series of works is focused on overcoming technological barriers and indicating the possibility of manufacturing finished products by means of the hydroextrusion method. The presented issues concern both materials susceptible to plastic deformation, such as aluminium alloys, and materials difficult to deform, such as titanium or austenitic steel, as well as case-hardened materials or powder materials. The paper describes original technologies enabling the production of finished products such as high-strength fasteners or highly durable electrodes for spot welding from materials with a highly fragmented microstructure. These products are currently being marketed.
