Extruded Aluminium Alloy

Severe plastic deformation processes like equal channel angular extrusion (ECAE) have been widely investigated for their ability to produce nano/ ultra fine-grained microstructures. It is well known that submicron sized grains/ sub grains can be produced in most Al alloys using this technique. However, industrial applications of ECAE will depend heavily on the advantages conferred by this process when it is used as an intermediate processing step prior to conventional forming. In the current investigation, the influence of pre processing by ECAE on subsequent post processing by conventional cold extrusion has been investigated. ECAE extrusion was carried out on cylindrical specimens of AA 6101 using an ECAE die with a die angle of 120 degrees. Extrusion was carried out for three passes using two different processing routes. The ECA extruded specimens were subsequently subjected to conventional cold extrusion. The differences in extrusion pressures, which have a strong influence on industrial applications, were noted. Changes in microstructure and mechanical properties were also determined. The obtained results of mechanical properties and microstructure evaluation show that for high strains (strain ε ≈ 2.01), ECAE through some processing routes can be effectively used as an intermediate processing step prior to conventional cold extrusion to obtain a product with enhanced mechanical properties.

Microstructure Morphology

The microstructure and mechanical properties of magnesium alloy AZ61wtih1% Sn addition has been studied in this paper. The results show that the addition of 1% Sn can refine the grain size and improve the microstructure morphology of β-Mg17Al12 phase. The addition of Sn can cause the formation of Mg2Sn phase in AZ61 alloy, which can effectively enhance the mechanical properties of magnesium alloy AZ61 at room temperature and 150°C.

Microstructure And Mechanical Properties

The as-cast Mg-14Li-3Al-(0-0.9)RE alloys were prepared with vacuum melting method, then processed by hot extrusion. The microstructure and tensile properties were investigated. The results show that both addition of RE and extrusion deformation can refine the grain size. Al3La compounds are formed with addition of La-rich misch metal. The as-extruded Mg-14Li-3Al-0.6RE alloy obtains the finest grain size (4.28 μm) and the highest mechanical properties (σb=222.75 MPa, δ=23.8%), which is related to the grain refinement and the formation of Al3La.

Thermal Conductivities

The thermal conductivities of quaternary Mg-Zn-Ca-MM alloys have been investigated by evaluating the effect of MM on Mg-4Zn-0.5Ca alloys, with an emphasis to develop a new Mg alloy without compromising thermal conductivity, process-ability and mechanical property. As a result, the thermal conductivity of 0.5 wt.% MM-added Mg-Zn-Ca alloy was almost same as that of MM-free Mg-Zn-Ca alloy. However, with further increasing MM contents, thermal conductivities of MM-added alloys decreased. The tensile yield strength was improved with increasing MM contents. In addition, the average spiral flow lengths of Mg-Zn-Ca-xMM alloys were almost same levels with Mg-Zn-Ca alloy.

There are a number of techniques for physical simulation of multistage metal plastic deformation processes. Analysis of these techniques in terms of stress-strain state schemes is presented. The purpose of described research is to compare microstructure and mechanical properties of two pipe steels processed by laboratory rolling mill with microstructure and mechanical properties of the same steels processed by thermomechanical simulator Gleeble-3800 with four different mobile convert units (MCU): MaxStrain, Torsion, HydraWedge and Pocket Jaw. Obtained results clearly show that proposed "tension-compression" technique developed for Gleeble Pocket Jaw MCU is theoretically and experimentally proved and can be successfully used for simulation of complex multistage metal plastic deformation processes, such as rolling, forging, stamping, etc.

Magnesium alloys have been known as the best lightweight metallic materials for various applications of electronic equipments and automobile parts due to high specific strength and stiffness. The needs for wrought magnesium alloys have been increased for the application to structural parts in the form of sheets and bars. However, magnesium has a hexagonal closed-packed (HCP) crystal structure with a limited number of operative slip systems at room temperature, and its formability is restricted to mild deformation. The improvement of the formability of magnesium sheets for real applications is important. In order to increase formability of magnesium sheets at elevated temperature, one promising way is a grain refinement.
