Witryna1 lut 2024 · The remaining grains with extensive IMC formation have α-angles of 13° and 10°. However, the grains on the left-hand side have α-angles of 82° and 59°, and they did not have obvious IMC growth. Fig. 2 (d) illustrates the grain orientation for the remaining grains in Fig. 2 (b). As can be seen, the grains have low α-angles of 17° … Witryna9 mar 2024 · Arc welding of aluminium and steel joins are commonly inundated by the formation of brittle intermetallic compounds (IMC) at the aluminium-steel interface. As the formation of IMC is closely related to the heat input into the base metals, it is hypothesised that the ability to regulate the heat input would enable the control of the …
