“…But the GBPs get coarser after RRA heat treatment which means higher corrosion resistance. Pankade et al, 36 investigated the effects of RRA and a heat treatment called duplex aging on the mechanical properties and electrical conductivity of 7075 aluminum alloy. Difference between Duplex aging and RRA is that, in duplex aging in contrast to RRA there exist just one heating and cooling cycle.…”

The intention of authoring this paper was giving the report of reviewing task of the previous researches done on the strengthening mechanisms and heat treatment of 7xxx aluminum alloys. The overall conclusion is that, the most powerful and so the most common strengthening mechanism in 7xxx alloys is the precipitation hardening (T6 heat treatment). On the other hand, stress corrosion is a problem in T6 treated 7xxx alloys, to address which, researchers have turned to special heat treatment called RRA (retrogression and re-aging) which picks the strength from T6, and stress corrosion resistance from T7x heat treatments.

Thermal management in hybrid Photovoltaic/Thermal (PVT) collectors is essential to derive electrical and thermal energy from a single system. Effective removal of heat gained by the photovoltaic module during its operation is possible with a proper thermal absorber design. Hence, thermal absorber design has gained prominence, and various design techniques were attempted in the literature to enhance energy delivery among different stakeholders. Most research groups tried to design absorber configurations attached to the PV panel's front or rear side. Absorber design configurations include various channel materials and geometry as well as other physical parameter combinations. The quantitative thermal energy delivery from the system could vary based on the absorber configuration and be useful for different applications. This study reports a detailed review to understand the relation between thermal absorber design configurations and the potential energy recovery from PVT systems. This study helps the designers identify channel designs, materials, and adequate working fluids for enhanced heat transfer to anticipate better thermal management of PVT systems. Challenges and suggestions to develop state of the art thermal absorber designs for relative commercial thermal applications using PVT systems are conveyed.

“…Recently, experimental studies on subsequent heat treatment (SHT) have been actively conducted to improve the conductivity of metallic materials [11,12]. The SHT is a process of natural cooling at room temperature after storing all components in a 150 °C chamber for 24 h prior to assembly.…”

Practical methods to mitigate level and variation of passive intermodulation with respect to time and temperature of coaxial cavity type duplexer are proposed through a variety of experimental results. From the findings derived in this study, a stable passive intermodulation response with less than 1 dB variation was shown in the environment temperature range of −10-85°C. The duplexer with time-stable PIM response at room temperature had a stable PIM value even in the environment temperature range.
