Tensile deformation characteristics of a nano-structured 5083 Al alloy

Effect of applied pressure on microstructure development and homogeneity in an aluminium alloy processed by high-pressure torsion

“…Although it is consistently reported that the strengthening of metallic samples is a direct consequence of the SPD processing [1], the mechanical properties of the present Al5Mg alloy significantly exceeds the properties reported in less dilute Al-xMg (0.5-4%) alloys processed by various SPD methods [41][42][43][44][45][46][47][48] and it may be compared even with the results obtained from samples containing higher amount of magnesium processed by ECAP [49] or HPT [50]. To place these results in perspective, Table 3 summarizes the mechanical properties of Al-Mg alloys processed by a number of different SPD methods [3,[41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56].…”

“…2 for discs processed through 1/4 revolution, the values of the microhardness in the peripheral regions are higher when processing with a pressure of 6.0 GPa than at 1.0 GPa. In the central parts of the discs, refined grains are formed after 1 turn for the disc processed at 6.0 GPa other Al-xMg alloys using data summarized in Table 3 [3,[41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] Table 1 Average grain size in sections parallel to the disc planes: data from centres and edges measured for both applied pressures.

Macro-performance evaluation of friction stir welded automotive tailor-welded blank sheets: Part II – Formability

“…As for the brittleness of 5083-H18, it failed without strain localization as confirmed by Menzemer and Srivatsan (1999) and Chang et al (2005) for similar materials. The macroscopic failure mode of aluminum alloy 5083 treated by strain hardened temper is brittle even though the microscopic features reveal locally ductile mechanisms like voids and shallow dimple.…”

Experimental Investigation of Microstructure and Mechanical Properties of Al 5052 Processed by Equal Channel Angular Pressing Technique

“…When the microstructures and mechanical properties of commercially pure titanium [12] are experimented using multi-pass ECAP process and cold extrusion, an increment in ultimate tensile strength from 791.9 to 292.5 MPa is observed with considerable microstructure refinement. The properties of AA5083 alloys investigated using ECAP are reported in [13][14][15][16].…”
