“…The yield and ultimate tensile strength of IR30-6H are higher than those of RH30-6H. According to our previous experiment, using a rapid solution heat treatment method (salt bath) can increase strength [9]. Thus, it is reasonable to suggest that the IR-heated specimen achieved higher tensile strength due to rapid solutionization.…”

“…Figure 4b shows the hardness of the specimens after 7 days of natural aging. The common solution heat treatment time for 6082 aluminum alloy is 120 min [9,11]. On both IR-heated specimens and RH-heated specimens, the hardness values become identical after 30 min of solutionizing.…”

“…However, the heat transfer media used in the fluidized bed (fine hard media, such as sand) is inconvenient for reheating and recycling. Using a salt bath method can reduce the duration of heat treatment and enhance the yield strength of 6082 extruded specimens [9]. However, salt bath heating is a liquid state heating method, and there is a danger that the salt particles will erupt and explode due to rapid cooling by water, causing a potential safety problem, and thus has been banned in many countries.…”

“…However, salt bath heating is a liquid state heating method, and there is a danger that the salt particles will erupt and explode due to rapid cooling by water, causing a potential safety problem, and thus has been banned in many countries. Additionally, rapid infrared (IR) heating method had been used as a rapid heating method to curtail the pre-heating duration of forging process [9], in an IR heating furnace, heat transfer occurs via convection and radiation. The method is thus clean and has a rapid heating rate and accurate temperature control [10].…”

Post-forging heat treatment is often necessary to achieve the mechanical properties required for aluminum alloy forged parts. In this study, hot-forged 6082 suspension parts are used to study the effect of rapid infrared (IR) heat treatment. The insoluble particles present in the matrix after the solutionizing process are observed. Experimental results show that using rapid IR heat treatment leads to superior solutionizing, and thus a larger critical onset strain in serrated tensile flow. The rapid IR heat treatment also had a more significant precipitation effect, which enhanced the mechanical properties of the material.

“…On the other hand, using sheet heating methods with high efficiency can also improve hot stamping productivity, such as resistance heating, induction heating, contact heating and direct flame impingement (DFI) heating. Studies show that quick heating will not deteriorate the performance of aluminum alloys [5,16,24]. Furthermore, a higher heating rate inhibits grain growth, which is beneficial for part performance.…”

Application of the hot stamping process on heat-treatable aluminum alloys effectively solves the problems of large springback and poor ductility during forming at room temperature, which expands the range of applications of aluminum alloys in the transportation industry. Sheet heating plays an important role in the hot stamping process, and increasing the heating rate can improve the hot stamping efficiency to some extent. In this paper, the feasibility of applying contact heating techniques with higher heating rates in the hot stamping process was studied. A contact heating device was designed, and the temperature distribution of the device contact surface was observed. Furthermore, the heating characteristics of 7075 aluminum alloy sheets during the contact heating process were explored by experiments and finite element simulation. Finally, the rapid solution treatment of aluminum alloy was carried out with a contact heating device, which was compared with the furnace heating solution treatment. The experimental and simulation results indicate that the device contact surface has a relatively uniform temperature distribution, and the aluminum alloy sheets can be heated to close to the set temperature in 15 s using contact heating techniques. Meanwhile, the rapid solution treatment of aluminum alloy sheets can be achieved within 15–20 s by contact heating techniques, obtaining superior mechanical properties. This suggests that the contact heating process can be used for rapid heating and rapid solution treatment of aluminum alloy sheets in hot stamping process.
