Twist Extrusion as a Potent Tool for Obtaining Advanced Engineering Materials: A Review

View full text Add to dashboard Cite

Twist extrusion (TE) is one of the most popular techniques of severe plastic deformation, aiming at imparting to a material a tailored microstructure and the associated property improvement. The article provides a survey of the literature on the mechanics of TE and the effect it has on the structure, texture, and the attendant properties of various materials, including metals and alloys, powder materials, and polymers. Special emphasis is placed on vortex flow during TE and its hitherto unexplored potential for producing micro-and macrostructures that promise superior properties of the materials. In particular, the possibility of creating novel hybrid materials with chiral inner architecture is demonstrated. The survey is concluded by a presentation of examples of practical applications of TE.

“…Gaining such knowledge will signifcantly expand the feld of SPD technology application as well as understanding the processes of transformation of constructional material with UFG structure. Terefore, material processing using SPD and traditional metal forming processes are also being actively studied [7,[9][10][11].…”

“…For mass applications, continuous processes of long billet deformation are developed intensively; in particular, diferent rolling processes are combined with severe plastic deformation [9,10,12,13]. In this case, the material after SPD becomes a semifnished product for subsequent rolling.…”

“…A number of studies point out an additional increase in the strength of parts made of alloys in the UFG state after subsequent plastic deformation. Te efect of combining the twist extrusion method of SPD and rolling on the structure and properties of the titanium grade 1 surface layer in the UFG state was studied in [9]. Te combined methods are also used to manufacture certain types of parts [16].…”

The article considers one of the combined methods of severe plastic deformation (SPD), which includes twist extrusion (TE) and subsequent rolling. The use of combined forming methods is promising for industrial use. Titanium grade 1 was used as a material in the experiments. Rolling was carried out in three stages with a decrease in temperature from 350°C to 180°C for a number of passes with one heating. The accumulated strain degree was e = 4.6 at twist extrusion and e = 3 in rolling. Increasing the reduction per pass decreases the number of heatings and increases the efficiency of the rolling process in whole. At the same time, it is necessary to set the maximum processing modes at which recrystallization processes do not occur in the billet. When rolling, the deformation degree in one pass was taken in the range of 5–20% with an increase in successive passes. The use of such deformation degrees allowed reducing the grain size in titanium grade 1 significantly. Twist extrusion reduces the grain size to 300–500 nm. Subsequent rolling allowed reducing the size of structural elements to 50–100 nm and provided a significant increase in the mechanical characteristics of the billet material (up to 869 MPa) while maintaining satisfactory ductility (up to 11.6%). It was found that increasing the deformation degree in one pass up to 40% at cross-rolling and simultaneously increasing the temperature to 385°C led to a decrease in the UFG structure quality and reduced strength of the deformable material by starting the dynamic recrystallization process.
