“…7(c1, c2, and c3) in solid triangles, respectively. For comparison, data for the same reaction system from other studies [6][7][8][9]11,12] and [23,24] are also plotted on the same figure with open symbols. The data for 430-SS and pure iron match very well with other results in the linear regression.…”

Lap joining of a pure aluminum plate and a low carbon steel plate was performed using friction stir spot welding. The aluminum plate was placed over the steel plate, a rotating welding tool was inserted into the aluminum plate, and the tip of the tool was dwelled above the aluminum/ steel interface. Dwell time was controlled in the range of 0 to 120 seconds. The microstructure of the welding interface was examined by optical microscopy and scanning electron microscopy. Chemical composition analysis was carried out by energy dispersive X-ray spectroscopy. Welding was achieved for all dwell times. Refined grains were formed by plastic flow in the aluminum matrix close to the welding interface. Intermetallic compound layer was produced along the welding interface. Precise backscattered electron image observation and energy dispersive X-ray spectroscopy analysis revealed that the intermetallic compound layer consisted of an Al 13 Fe 4 phase layer and an Al 5 Fe 2 phase layer. The thickness of the layers increased in proportion to the square root of the dwell time. The parabolic coefficient K was 1:30 Â 10 À14 and 6:06 Â 10 À13 m 2 /s for the Al 13 Fe 4 layer and the Al 5 Fe 2 layer, respectively.

“…Diffusion coefficients in the iron-and nickel-based bond coat couples at 500ºC and 700ºC were also lower than those reported by Hirano et al [56]. In addition, Jindal et al [57] reported rapid growth of iron aluminide at the interface of diffusion couples at 500ºC to 600ºC made by roll bonding pure iron and aluminum [57]. No iron aluminide was found in the SAE 1040 couples in this study at 500ºC or 700ºC probably due to the alumina contamination previously discussed.…”

“…The high purity, low-carbon iron used in the study by Jindal et al [57] was inferred to have led to the rapid formation of the interlayer. High purity, low-carbon iron was also used by Hirano et al [56].…”

Concentration and flux profiles for SAE 1040-BT1 and Fe26Cr8Al0.4Y-BT1 diffusion couples held at 700ºC for 500 hours. Note the positive flux for cobalt diffusion in in the Fe26Cr8Al0.4Y-BT1 couple in contrast to the for the Ni base bond coats. Note the lower aluminum flux in the SAE 1040-BT1 couple as well as the interlayer phase developing in the Fe26Cr8Al0.4Y-BT1 couple at ~50 atom fraction.
