“…The sequence of Cr phases is solid solution → G.P zones → fcc-Cr phase → order fcc phase → bcc-Cr phase [ 22 ], and the formed stable bcc-Cr phase structure has Nishiyama–Wasserman (N-W) or Kurdjumov–Sachs (K-S) ORs with a Cu matrix [ 23 , 24 ]. At the same time, the fine and dispersed precipitates at high temperature can also inhibit the recovery and recrystallization transformation by the pinning effect of dislocation and substructure, which is a critical means to increase the softening resistance of the alloy [ 25 , 26 ]. However, the growth and coarsening of the precipitate during the over-aging stage of the Cu-Cr alloy accelerate the softening, which has a significant impact on the processing and service temperature of the alloy.…”

The relationship between microstructure evolution and properties of a Cu-Cr-Sn alloy during aging and high-temperature softening was investigated in detail in the present work. The results show that the addition of Sn refines obviously the size of the Cr phase and enhances the thermal stability of the alloy, which improves the peak-aged hardness of the Cu-Cr-Sn alloy reaching 139 HV after aging at 450 °C for 240 min. In addition, the recrystallization behavior of the Cu-Cr alloy with the 0.12 wt.% of Sn at high temperature is also significantly inhibited. Lots of precipitated Cr phases and a high density of dislocations are found in the Cu-Cr-Sn alloy annealed at high temperature, resulting in the softening temperature of the Cu-Cr-Sn alloy reaching 565 °C, which is higher than (about 50 °C) that of the Cu-Cr alloy.

“…As a result, the wear loss decreases [98]. Kumar et al [55] reported the effect of different sliding speeds (1.39 and 2.60 m/s) on the wear performance of the AZ91/TiC composites. They found that the wear rate increased from 1.39 m/s to 2.60 m/s for all the samples.…”

“…It can also be seen that the particle size and shape are not uniform; therefore, small voids may occur thanks to discontinuous reinforcements, which causes an increase in the porosity of the composites.

The demand for magnesium (Mg) alloys is increasing in many industries, such as automotive and aerospace, thanks to their low density and high specific strength. However, the poor tribological performance of Mg alloys is one of the most important disadvantages that limit their widespread use. Researchers have developed different approaches to improve the wear performance of Mg alloys, such as alloying, coatings, surface modifications and composite production. Wear performance of systems with sliding parts are crucial for a lifetime and energy efficiency. The development of Mg matrix composites can significantly reduce energy loss by reducing damage from friction and wear. For this reason, it is crucial to understand the wear behaviour of recent Mg matrix composites. The effect of different parameters such as load, sliding speed, reinforcement content, reinforcement type and temperature on the wear performance of Mg matrix composites were investigated.
