Development of technological production process of biocompatible magnesium tubes for medical appliions is the subject of the present paper. The technology consists of two stages—extrusion and dieless drawing process, respectively. Mg alloys for medical appliions such as MgCa0.8 are characterized by low technological plasticity during deformation that is why optimization of production

Function of Part: Light weight, Shock absorption Alloy Used: AM60B/AM50A. DESCRIPTION. Mg Alloy frame for children’s bicycle is a kind of technological breakthrough from the traditional welding of iron and aluminum frames. Mg alloy frame produces a unibody adopting magnesium alloy extrusion process and replaces the traditional welding technology.
In order to research the dynamic recrystallization (DRX) and grain refinement mechanisms in the process of extrusion through the rotating container, hot compression experiment of AZ31 magnesium alloy was carried out. Through the coination of experimental data and Yada empirical model, the DRX model of AZ31 magnesium alloy was established.
In preliminary extrusion trials of alloy AZ80 carried out at 100 °C, cold cracks could be observed on the surface of the rods. Therefore, for this magnesium alloy the trial temperature was increased up to 110 °C. Table 1 summarizes the param-eters of the extrusion experiments. As is known from conven-

Billets of magnesium alloy AZ31 were extruded and the required extrusion force was measured vs. process time. After the extrusion tryouts the manufactured hollow profile sections were measured with respect to the obtained wall thickness, inner and outer diameter of the thin-walled and the thick-walled sections, and in the wall thickness transition areas.
