The AL-6061 stress-strain curve at different temperatures was obtained from the compression test of the universal material testing machine. The friction factor between Al-6061 alloy and die is determined by ring compression test.The stress-strain curve and friction factor are applied to the finite...
(f) Stress-strain curves of the as-built and T6 heat-treated TiB2-reinforced AlCuMgFeNi alloy [290]. 6.2.3 Wire-arc additive manufacturing Until now, WAAM technology has been implemented to tailor the microstructure or mechanical properties of alloys by adding ceramic particles [243,292]. ...
Grain size greatly influences mechanical strength, as elucidated by the Hall–Petch relationship [66,67] (σy=σ0+k/d), which shows that the yield strength (σy) of polycrystals is inversely proportional to the square-root of grain size (d), where σ0 is the frictional stress (which is...

An unloading/reloading process was used to generate a straight stress-strain line for higher measurement precision, while avoiding any damage to the reinforcements during the procedure. Using repeated unloading and reloading at room temperature, the elastic modulus of the composites was reduced during ...
At the same time, according to the flow stress curve at strain rates of 0.1 s−1 and 1 s−1, the flow stress of the furnace-cooling homogenized billet HT6 was slightly lower than that of the as-cast billet, indicating that the extrusion break-through force of the furnace-cooling ...
Therefore, the aging precipitation behavior of the alloys was studied from 120 to 185 °C, and the resulting hardness and tensile stress–strain curves of both aged alloys are shown in Fig. 2. The initial hardness (62 HV) of #2 alloy was higher than that of #1 alloy (56.1 HV), as ...
