Examples
example 1
[0036] Example 1: Mg-80%TiB 2 Preparation of grain refiner
[0037] (1) Dry mix 55.10% titanium powder, 24.90% boron powder and 20% magnesium powder on a mixer for 12 hours by weight, then cold press into a prefabricated block with a relative density of 45%, wrap it with aluminum foil and dry it processed and buried in corundum crucibles;
[0038] (2) Use a box-type resistance furnace for isothermal treatment at 900°C for 100 minutes;
[0039] (3) Take out the prefabricated block to make Mg-80%TiB 2 grain refiner;
[0040] (4) After adding 0.5% of the grain refiner to the AZ91D magnesium alloy, the grain size of the alloy can be reduced from 96 μm to 53 μm.
example 2
[0041] Example 2: Mg-50%TiB 2 Preparation of grain refiner
[0042] (1) Dry mix 34.44% titanium powder, 15.56% boron powder and 50% magnesium powder on a mixer for 10 hours by weight, then cold press into a prefabricated block with a relative density of 50%, wrap it with aluminum foil Dried and buried in a corundum crucible;
[0043] (2) Use a box-type resistance furnace for isothermal treatment, and hold at 800°C for 120min;
[0044] (3) Take out the prefabricated block to make Mg-50%TiB 2 grain refiner;
[0045] After adding 1.4% of the grain refiner to the AZ91D magnesium alloy, the grain size of the alloy can be reduced from 96 μm to 58 μm.
example 3
[0046] Example 3: Mg-20%TiB 2 Preparation of grain refiner
[0047] (1) The titanium powder that is 13.78% by weight, the boron powder of 6.22% and the magnesium powder of 80% are cold-pressed into the prefabricated block of relative density 48% after 8 hours on the mixer, dry after wrapping with aluminum foil processed and buried in corundum crucibles;
[0048] (2) Isothermal treatment at 850°C for 180min in a box-type resistance furnace;
[0049] (3) Take out the prefabricated block to make Mg-20%TiB 2 grain refiner;
[0050] After adding 1.5% of the grain refiner to the AZ91D magnesium alloy, the grain size of the alloy can be reduced from 96 μm to 56 μm.
