Effect of High Magnetic Field on Phase Transformation of 7085 Alloy during Homogenization
The microstructural evolutions of 7085 alloy during high magnetic field homogenization were investigated. The as-cast microstructures of 7085 alloy consist of eutectics α+ AlZnMgCu, Al7CU2Fe, and AlTiCuFe. During homogenization, α+ AlZnMgCu eutectics become discontinuous and spheroidized, some transform into Al2CuMg(S). High magnetic field significantly accelerates the melting of AlZnMgCu and S phase. The optimum homogenization result is obtAlned at 460℃/10h +480℃/8 h under 12T magnetic field.
