Structural heredity between Al5Ti1B and AlTi, AlB master alloys
（College of Materials Science and Engineering; Shandong University of Technology; Jinan 250061; P. R. China）
Abstract:Al5Ti1B master alloy was produced by two-step method. Experimental results show that the structure of Al5TilB master alloy depends on that of AlTi and AlB master alloys, the morphologies of TiAl3 depend on AlTi master alloy and the boride phases depend on AlB master alloy. There are remarkable structure heredity between Al5Ti1B master alloy and AlTi, AlB master alloys. Theoretical analyses show that AlTi and Al-B master alloys can change the melt structure of Al5Ti1B master alloy, then affect the solid structure of the master alloy.
Key words: Al5Ti1B master alloy; AlTi and AlB master alloys; grain refinement
