“…5(a), the shapes of the load-depth curves were affected by residual stress at different stages; compressive residual stress shifts up the loading stage and steepens the unloading stage, and vice versa. This effect of residual stress on the loading stage has been observed in experiments for various types of materials [15][16][17][18][19]. The effect on the unloading stage has been well investigated in experiments for alloys with different crystal structures such as copper (Cu), ruthenium (Ru), aluminium (Al), titanium (Ti) and steel [16,20] as shown in Fig.…”

In this study, residual stress in Sn-3.0Ag-0.5Cu lead-free solder after annealing at varying temperature and duration was investigated by nanoindentation and uniaxial tensile experiments. Based on the unloading response of load-penetration depth, the contact stiffness was theoretically calculated and found to be decreased with increasing annealing duration especially at the annealing temperature of 210°C. Additionally, the effect of residual stress on constitutive behaviour at strain rates of 1×10 −3 s −1 , 5×10 −4 s −1 and 1×10 −4 s −1 was consistently observed. By correlating residual stress and elastic indentation recovery, it was confirmed that greater contact stiffness is induced by greater compressive residual stress. Therefore, the optimal annealing condition of SAC305 solder is 210°C for 12 h, which is believed to minimize the residual stress and stabilize the mechanical property of annealed solder.

“…The seemingly weak matrix/boride interface does not occur • in composites containing AlB 2 . These fl aws in the as-cast Al-Si/AlB • 12 composites are also causing the fracture of the particles upon nanoindentation of the dodecaboride. The sum of all these factors contributes to the lower values • of Rockwell hardness obtained on bulk composites containing dodecaboride particles when compared with Al-Si/ AlB 2 composites.…”

“…The distribution of the elastic modulus and hardness through the array of indents are shown in Figure 8 A-D for the diboride-and dodecaboride-containing samples, respectively. It has been reported that nanoindentation hardness of reinforced aluminum alloys increases for residual compression stresses and decreases in tension [12] . On the basis of these fi ndings, it is possible to infer that the boride particles studied in this work are in compression with respect to the aluminum matrix because of the tendency to increase hardness as the indents approach the particle.…”

The mechanical properties of centrifuged Al-Si-B composites containing aluminum diboride and aluminum dodecaboride particles were studied using optical and scanning electron microscopy (SEM), hardness tests, and nanoindentation. SEM was used to further analyze the Rockwell indentations, while nanoindentation experiments were completed on the matrix and the reinforcing particles. The outcomes of this study were compared with the results obtained in superfi cial Rockwell hardness and Vickers microhardness tests to determine which of the boride reinforcements was more benefi cial for the mechanical properties of the Al-Si matrix composite. Aluminum diboride was found to improve bulk mechanical properties more than did aluminum dodecaboride particles. On the other hand, aluminum dodecaboride showed to be a better reinforcement at the micron and submicron scales, as revealed by nanoindentation experiments. A discussion of these fi ndings helped understand the underlying mechanisms behind this apparent discrepancy.

“…It also develops a greater temperature rise in the cutting zone, which results in more damage on the surface of the composite. This is due to the high linear temperature expansion coefficient of the aluminum based composite (Olivas, Swadener, and Shen 2006). This implies that the control of the temperature is more crucial during machining, to achieve good dimensional accurate products (Kannan and Kishawy 2008).…”

This study presents an effective approach to assess the machinability of 6351 aluminum alloy matrix, reinforced with 5 wt. % Silicon Carbide (SiC) and (0, 5 and 10 wt. %) Boron Carbide Downloaded by [University of Nebraska, Lincoln] at 05:28 01 October 2015 2 (B4C) particles. The turning tests are carried out with a Polycrystalline Diamond (PCD) tool to identify the effect of the B4C particles addition to the composite, with an objective to improve the Material Removal Rate (MRR) and to reduce the Surface Roughness (Ra) and PowerConsumption (P). The significant level of each factor, which contributes to affect the output response, is found through Analysis of Variance (ANOVA). The results show that the inclusion of B4C particles in the hybrid composite significantly affects the machinability, with a contribution to the Surface Roughness by 7.87% and P by 6.36%. The increase in MRR affects the quality of the material, irrespective of the composites.
