“…According to the previous studies [2,4], the tensile strength of Ti-6Al-4V alloy improved when the treatment temperature was 1173 K or higher. However, the ductility greatly reduced if the treatment temperature was higher than the β transformation point (1271 K).…”

“…From this viewpoint, we investigated the effect of short-time heat treatment on the mechanical properties and the fatigue strength of Ti-6Al-4V alloy [2][3][4][5]. The most effective heat treatment was composed of a first heat treatment at 1203 K for 60 s (quenching) and a second heat treatment at 853 K for 40 s (air cooling).…”

“…Owing to this attractive potential, many studies have investigated for heat treatments to obtain various microstructures and their effect on the mechanical properties of the alloy. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] One of the well-known heat treatments is solution treatment and quenching plus aging. With this series of heat treatment, the tensile strength of Ti-6Al-4V alloy is increased by the transformation of phase to 0 martensite phase and its decomposition to fine and phases.…”

“…17) We thus further investigated the effect of short-time duplex heat treatment, consisting of solution treatment at 1243 K for 60 s and quenching plus aging at 773 K for 40 s, on the mechanical properties of the alloy. As a result, while the tensile strength was remarkably increased from 1110 to 1450 MPa, the reduction of area was decreased from 36 to 17%.…”

The effect of short-time duplex heat treatment on the microstructure and mechanical properties of Ti-6Al-4V alloy was investigated. This heat treatment consisted of solution treatment at 1203 K for 60 s and subsequent water-quenching plus aging at 753, 853 and 953 K for 40 s. The yield strength and tensile strength of the alloy were significantly increased by the above heat treatment and their maximum improvement rates reached about 25%. It was thought that this strengthening was caused by the formation of 0 martensite phase with quenching after the short-time solution treatment and the precipitation of fine phase in the retained phase during the short-time aging. In spite of the remarkable improvement in the strength, the ductility of the heat-treated materials remained above the level of the non-treated material, most likely because strain-induced martensite transformation occurred in phase which was retained even after the short-time aging.

Application of High-Frequency Induction Heating Apparatus to Heat Treatment of 6061 Aluminum Alloy

2011

View full text Add to dashboard Cite

A high-frequency induction heating apparatus was used for the heat treatment of a commercial 6061 aluminum alloy bar with the objective of improving the mechanical properties and productivity. Heating states of the 6061 alloy bar were examined in terms of temperature distribution, heating rate, overheating and temperature fluctuation; moreover, the mechanical properties of the alloy after heat treatment were also investigated. The results of this study are as follows. When the 6061 alloy bar was rapidly heated to the heat treatment temperature using the induction heating apparatus, temperature distribution and overheating of the sample were small as well as the temperature fluctuations in the holding process. A rapid heating rate of about 21 C/s heated the sample to the heat treatment temperature of 560 C in 26 s. The sample showed equivalent or superior mechanical properties compared with a sample heated by conventional electric furnace. Temperature and time of the heat treatment process greatly influenced the mechanical properties of the 6061 alloy, while there was no significant difference in mechanical properties of the sample heat-treated at various heating rates.
