The present study focuses on developing lightweight assembly of two different aluminium alloys extruded and high pressure die cast (HPDC) for battery frame assembly in BEV. The goal is to produce defect-free …
As an important part of the battery pack, the design, material selection and manufacturing process of the new energy battery tray have attracted tremendous attention from the …
Aluminium alloy chips were cold pressed at different pressures to determine the compressibility curve. A floating cylindrical die with 25 mm of diameter was used.The samples, previously cold pressed at 650 MPa, were submitted to hot pressing at 500 C in a cylindrical mould with graffito as lubricant. ...
Mg−3.18Al−1.00Zn−0.06Mn(wt.%) (AZ31) alloy was fabricated through a combination of hot die forging at 300℃ and extrusion processes (HFE). Results demonstrate that the HFE process can accelerate dynamic recrystallization (DRX) and refine grains effectively while weakening the basal texture intensity. The highly uniform fine …
Section snippets Preparation of materials The chemical composition of the as-cast AP65 alloy is 6.15 wt.% for Al, 5.28 wt.% for Pb, 0.58 wt.% for Mn, and the balance is magnesium.This alloy was prepared using an induction melting at 750 C and manganese was added into the liquid magnesium in the form of Al–30 wt.% Mn intermediate alloy …
a Engineering stress–strain curves of studied samples in both tension (smooth lines) and compression (pointed lines), where table including tensile yield strength (TYS), ultimate tensile strength (UTS), tensile strain (ε T), compressive yield strength (CYS), ultimate compressive strength (UCS) and compressive strain (ε c); b representative …
Hot extrusion is one of the important processes used to produce these hard aluminium alloys. It is generally accepted that product properties are closely correlated to microstructure. So it is of paramount importance to understand the way in which the structure is modified and how the forming parameters (i.e. container …
Homogeneous heat treatment serves the significant roles in eliminating the segregation and tuning the microstructure of alloy ingot. It usually cost tremendous power and time to achieve a homogeneous microstructure for aluminum alloys. In this article, the hot extrusion was directly introduced on the spray deposited aluminum alloy 7055 ingot …
In addition to strong deformation textures induced through hot extrusion, coarse grains are also greatly refined, which is attributed to the occurrence of dynamic recrystallization (DRX) [12,13 ...
As observed in previous experiments (Schikorra et al., 2007), slow cooling rates after the hot deformation of aluminum alloys provide enough time for static (secondary) recrystallization and have to be avoided for a clear investigation of the kinetics of dynamic recrystallization and restoration mechanisms. ...

The aim of this study is to develop and implement a new type of extruded profile concept to produce tight base assemblies for battery housings by a longitudinal …
Hot extrusion (HE) was applied in the treatment of low-cost commercial Al6063 alloy containing impurity iron (Fe) element (0.12 wt%) with the aim of decreasing the self …
A review of research on aluminum alloy materials in ...
Hot extrusion (HE) treated low-cost commercial Al6063 alloy was chosen as anode material in Al-air battery. The role of the HE treatment in the microstructure …
It is shown that the mechanism of deformation is either dynamic recovery or dynamic recrystallization, according to whether the alloy is of high or low stacking-fault energy. This leads to extrudate structures which either contain subgrains, ideally with no static recrystallization occurring, or grains formed by successive dynamic, metadynamic, …
The results show that the designed hot extrusion rim die meets the requirements of strength and deformation, and the best extrusion process parameters of …
We produce 6061T6 custom aluminum extrusions for electric vehicle battery trays (some customers request 6082T6 aluminum). The 6061 extruded aluminum is commonly used as structural material for new …
