[0041] Such as image 3 As shown, based on the above-mentioned preparation device, the present invention provides a method for preparing a dual-performance powder turbine disk with continuously changing crystal grains, which specifically includes the following steps:
[0042] Step 1. First, metal powders 5 with different particle sizes are loaded into the powder storage device 1 in batches;
[0043] The metal powder 5 of the present invention adopts single-alloy metal powder or double-alloy metal powder with a particle size of 15-250 μm. Among them, when the metal powder 5 is a single alloy, the metal powder 5 has a particle size of 15-53 μm and accounts for 15%-20% by volume, 53-106 μm accounts for 15%-20% by volume, and 106-150 μm accounts for 30%-35% by volume. %, 150-250 μm volume accounts for 30%-35%.
[0044] Step 2: Open the powder lowering port 11 at the bottom of the powder storage device 1, and the metal powder 5 falls into the corresponding position in the sheath ...
Embodiment 1
[0053] Example 1: For the preparation of a dual-performance powder turbine disk with a size of Φ500mm×60mm, specifically follow the steps below:
[0054] Preliminary preparation: making a dual-performance powder turbine disc casing 42 for filling metal powder 5, the casing 42 is made of stainless steel, and then preparing corresponding metal powder 5, such as selecting and heating the metal powder 5 Gas treatment and other operations, and finally set up the preparation device.
[0055] Step 1: first load metal powders 5 of different particle sizes into the powder storage device 1 in batches;
[0056] Among them, the metal powder 5 is a single alloy, the particle size of the metal powder 5 is 15-53 μm, the volume ratio is 20%, the particle size is 53-106 μm, the volume ratio is 20%, the particle size is 106-150 μm, the volume ratio is 30%, the particle size is 150-250 μm, accounting for 30% of the volume.
[0057] Step 2: Open the powder lowering port 11 at the bottom of the ...
