“…The grain size of the raw material was reported to be about 85 microns, while it was 10 microns for the tube produced by FSE. Asadi et al [17,18] used friction stir-back extrusion to produce brass wires from brass chips and developed a numerical model to simulate the process. They demonstrated the effects of process parameters, including tool rotational and advancing speed, on the strain and temperature distributions, microstructure, and material flow patterns, and concluded that, in the cross-section of the produced wire, the finer microstructure emerges in the sample periphery.…”

Friction Stir Extrusion (FSE), the focus of this research, is a process that has tremendous potential for shaping and improving the mechanical properties of the final product as well as the mechanical alloying. In this study, a cylindrical sample of LM13 aluminum, to which silicon powder is added, is extruded by the penetration of a tool and takes the shape of a tube. The microstructure of the aluminum tube produced is studied using a light microscope. Various tests, including compression and wear tests, are performed to evaluate the wear and mechanical properties of the tubes produced. Additionally, the process is simulated using the finite element method (FEM), and the strain and temperature distributions in the tubes are examined to understand the impact of tool advancing speed better. The strain and temperature are highest on the inner surface, where the tubes meet the tool. Moreover, as the advancing speed increases from 25 to 40 mm/min, the maximum temperature in the tubes increases from 350 to 400 °C. The surface quality of the samples is directly related to the advancing speed, so the surface quality improves as the advancing speed increases. The results obtained from the compression and wear tests show that the compression strength has increased by about 17%, and the wear resistance has improved by about 20%.

Friction stir extrusion (FSE) is a versatile technique that plays a dual role in sustainable recycling and shaping of materials. This method involves a rotating mandrel and a fixed matrix within a mold, where compressed waste metal chips or primary bulk materials are introduced. The rotating mandrel exerts continuous axial pressure, generating frictional heat that softens and bonds the materials together. As the mandrel advances, the materials are reshaped and extruded through the cavity inside the mandrel or the space between the mandrel and the matrix, resulting in the desired product, such as wires or pipes. FSE finds applications in recycling machining wastes, improving powder metallurgy products, producing wire raw materials, creating structures with fine microstructures, and developing new alloys and composites. The resulting materials exhibit refined grains, leading to enhanced mechanical and metallurgical properties. This review article compiles experimental studies exploring the mechanical and microstructural characteristics of samples manufactured using FSE for recycling, reshaping, alloying, or bilayer production. Additionally, it discusses various tool, mold, and machine designs proposed by researchers. Beyond its unique properties, FSE is highlighted as an energy‐efficient, sustainable, and eco‐friendly process.

To research the in uences of process parameters on a special extrusion-shear manufacture method for magnesium alloy rods, deform-3d software with nite element simulations has been used to analyze the material ows of deformed magnesium alloys AZ31B during the extrusion-shear (ES) process, as well as the grain sizes and distribution of extrusion loads, stresses and strains, and blank temperatures. Temperature elds, stress elds, strain elds and temperature elds varying with different blank preheating temperatures, extrusion speed and extrusion ratios were simulated. In uences ofdifferent extrusion conditions and different die structures on microstructures of rods prepared by ES process has been researched. Extrusion forces decrease with the increasing extrusion temperatures, decreasing extrusion ratios, increasing die channel angles and decreasing friction coe cients. The ow velocities of metal in the ES die increase with development of ES process. Increasing the channel angles and reducing the friction factors would increase the out ow velocities of metal, but it has little effect on the uniformity of metal ow. The increase in friction and extrusion speed would increase the temperatures of the ES die.The ES process can prepare ner and more uniform microstructures than those prepared by direct extrusion under the same conditions.
