During recent years, material characterization based on miniature tensile specimens has been investigated extensively. The Small Punch Test (SPT) is often used for determination of tensile properties but alternative miniature tensile specimen geometries have been suggested due to the limitations of the SPT specimen geometry. However, compared to SPT, the Micro-Tensile Test (M-TT) has a significant advantage since it does not need previous established correlations and enables direct results conversion into standard terms. In this paper, the applicability of the M-TT is investigated for material characterization including Lankford coefficients, hardening laws and stress-strain curves. For this purpose, mild steel DC01 M-TT samples were extracted from sheet in Rolling, Transverse and Diagonal Directions. Moreover, M-TT samples were machined to achieve different thicknesses for indicating thickness effects on strain path.

“…Many works have been conducted to identify the most reliable recycling process that benefits the environment and economy, finally solving the supply and demand of the primary source of aluminium alloy, including a combination with reinforcement materials [10], [12], [15]- [18]. The findings showed promising performance in terms of the strength of the material, which can be enhanced further using alumina oxide.…”

“…The findings showed promising performance in terms of the strength of the material, which can be enhanced further using alumina oxide. The study on material response and damage behaviour of recycled aluminium alloys undergoing finite strain deformation also has been considered in a few works; refer to [18]- [19]. It is generally agreed that such recycled material's deformation behaviour and fracture mode are still an open and exciting area to explore [25].…”

“…In addition, aluminium alloys were anisotropic materials that exhibit different responses for different orientations [17]. Many studies have contributed to the anisotropic influence on material behaviour when subjected to finite strain deformation [17], [18], [26]. The anisotropic deformation of metal is also associated with its mechanical behaviour during forming operations.…”

The deformation behaviour and fracture mechanism of reinforced recycled aluminium alloy are still an open and exciting area to be explored. Based on this motivation, this paper investigates the deformation behaviour, and fracture mode of recycled aluminium alloy AA6061 reinforced alumina oxide at a high strain rate using the Taylor cylinder impact test. The deformation behaviour analysis was also compared with the behaviour shown by the recycled AA6061 without reinforcement material. The geometric profile of the deformed specimen was used to analyse the deformation behaviour and fracture mode, including the relation with the impact deformation characteristics. Three different fracture modes were observed within the impact velocity of 190-370 m/s. The reinforced recycled AA6061 showed a better strength performance with higher critical impact velocity than the unreinforced recycled AA6061. The damage deformation behaviour was studied using Scanning Electron Microscope (SEM). The results showed that the damage agents were initiated, grew, and coalesced during mild ductilitydeformation. Damage progression was finally examined using ImageJ software and characterized average voids size. The decrement of voids size was quite significant under tensile splitting and petalling fracture modes compared to the mushrooming due to severe localized plastic strain deformation around this plastic deformation zone. Therefore, the increasing impact velocity increases the severity of damage progression of the reinforced recycled AA6061.
