Dissimilar transient liquid phase (TLP) bonding between stainless steel 310 and Inconel 617 was carried out using a BNi-2 interface layer. TLP joints were fabricated at 1040, 1070 and 1100 °C for a bonding time of 60 min. In addition to microstructural evaluations, the mechanical properties of different TLP joints were also studied. The results indicated that increasing the bonding temperature resulted in decreasing the solidification zones and accelerating the formation of the intermetallic com...

The paper analyses the fretting and wear behavior of pure copper and pure titanium coatings realized through cold spray. The coatings were designed and produced by employing processing conditions leading to minimum porosity and high hardness; these conditions were 700 °C and 40 bar for Ti powders and 400 °C and 30 bar for Cu ones. The low porosity and high strength materials led to high resistance to wear damaging through the optimal energy dissipation upon fretting. Due to the sprayed particles...

Commercially pure aluminum was deformed via the extrusion process at different strain rates considering the temperature rising during the deformation, i.e., with different Zener–Hollomon parameters (Z), to investigate the effect of Z on its grain structure and tensile properties in the micro/meso-scale. The results demonstrate that deformation-induced grain refinement was obtained by increasing the values of the Z. Besides, the dislocation density of the aluminum specimens increased with the str...

The 5083 aluminum alloy sheet was welded by metal inert gas welding with zirconium-containing Al-Mg alloy welding wire as filling material. Then the post-weld heat treatment was carried out at 130 °C for 3 hours and 320 °C for 1 hour, respectively. The results show that the effects of two annealing treatments on the MIG-welded Al-Mg joints are basically equivalent. After heat treatment, a large number of Al3Zr particles are precipitated in the weld zone of joints. These particles are coordinated...
The objective of this paper is to enhance service life of excavator bucket teeth for decreasing the idle time required to reinstate the teeth periodically during excavation process. To achieve this goal, medium-carbon steel was chosen with a chemical composition of 0.41C, 0.23Si, 0.75Mn, 1.0Cr, 0.23Mo (wt.%) to cast as Y-blocks with wall thickness of 30 mm using medium-frequency induction furnace. Optimum tensile strength (1492 MPa) and hardness (474 HV) were obtained for the sample quenched at ...
