Problems solved by technology

However, until now, people’s understanding of thermal fatigue of zinc-based alloys is still not very comprehensive. The quantitative research on thermal fatigue of zinc-based alloys in China is still relatively backward, and the problem of thermal fatigue in production practice has not been completely solved.
[0003] In summary, there are few systematic studies on the thermal fatigue properties of zinc-aluminum alloys.

Embodiment 1

[0009] The zinc-aluminum alloy composition is selected as (No. 1 sample), Si: 2.5%, RE: 0.1%, Ni-Ti (Ni50%, Ti50%): 0.1%, Cr: 0.1%, Al: 40%, Cu: 2.0 %, Mg: 0.01%, and the balance is Zn. The smelting process is as follows: first add aluminum ingots, aluminum-copper master alloys, aluminum-chromium master alloys, zinc ingots and an appropriate amount of Si and Ni-Ti alloys to the induction melting electric furnace. After complete melting, fully stir, add an appropriate amount of RE, and Keep warm for 5 minutes at 700-750°C to homogenize each element, and then use a bell jar to press the magnesium strips to reduce the burning loss rate. Use 0.2% zinc alloy degassing refining agent for degassing and refining, let it stand for 10 minutes, remove the slag, pour it when the temperature is 650-670°C, and then make it as figure 1 The sample shown.

[0010] The thermal fatigue test was carried out using a resistance furnace heating self-constraining thermal fatigue testing machine. T...

Abstract

The invention relates to a novel multielement thermal fatigue resistant zinc-base alloy, which is characterized by comprising the following compositions: 2.5 to 3.5 percent of silicon, 0.1 to 0.27 percent of rhenium, 0.1 to 0.2 percent of Ni-Ti (50 percent of nickel and 50 percent of titanium), 0.1 to 0.2 percent of chromium, 40 to 46 percent of aluminum, 2.0 to 3.0 percent of copper, 0.01 to 0.02 percent of magnesium and the balance being zinc. The novel multielement thermal fatigue resistant zinc-base alloy can obviously improve the thermal fatigue performance of zinc-aluminum alloy.

Description

technical field [0001] The invention relates to a zinc-aluminum alloy material, in particular to a multi-element zinc-based alloy capable of significantly improving the thermal fatigue performance of the zinc-based alloy. Background technique [0002] At present, the research on thermal fatigue of alloys mainly focuses on heat-resistant steels and high-temperature alloys, while the research on zinc-based alloys is relatively less. Cast zinc-based alloys have good mechanical properties, wear resistance and corrosion resistance, low density, moderate thermal conductivity and electrical conductivity, high ultimate tensile strength, good wear resistance, good bearing capacity, no magnetism, and no impact when colliding. Spark generation, vibration and noise reduction performance and low cost are widely used in various fields and bring significant economic benefits. A large number of studies on zinc-aluminum alloys have shown that through the alloying of trace elements, the crys...
