Example Embodiment
[0102] Example 1: Cu-1.0%, characteristic microalloying elements-Be, Mo, basic microalloying rare earth element-lanthanum La
[0103] (1) Weigh the required alloy elements according to the ingredient calculation table, as follows.
[0104]
[0105] (2) Add an appropriate amount of aluminum ingot to the melting furnace, heat it to melt completely and keep it at 700~800℃; in order to prevent the melt from inhaling too much air, the melting process should be as short as possible and in a closed environment carry out.
[0106] (3) Add Al-Mn, Al-Ti, Al-Be, Al-Mo, Al-Zr master alloy or mixed metal additives (including salt compounds) according to the formula ratio, and then add Cu pure metal and Al-Cd master alloy or mixed metal additives, then add B and rare earth element La, and stir evenly.
[0107] Mixed metal additives refer to cake-like or massive non-sintered powder metallurgy products used for adding and adjusting alloy components, including manganese, copper, zirconium, beryllium,...
