Thermal deformation rheological behavior of 6111 aluminum sheet for sale Haomei

In order to cope with the energy crisis and meet the development needs of the aerospace and automobile industries, structural lightweighting has gradually become a research hotspot in the processing field. suitable material for the board. At the same time, the parts made of 6111 aluminum sheets for sale have good thermal conductivity, which can effectively dissipate the heat of the engine, and 6111 aluminum sheet can reduce the weight by 50% compared with the steel parts under the premise of meeting the relevant strength requirements.

However, the forming ability of 6111 aluminum sheets at room temperature is poor, and it is difficult to process complex parts with traditional processing techniques. In response to the difficulty of forming aluminum alloys at room temperature, Mohamed proposed a hot stamping and cold quenching process for aluminum alloy sheets. This process Combining hot stamping and heat treatment, quenching is completed at the same time after hot forming to ensure that it obtains a supersaturated solid solution to obtain parts with complex shapes and high strength. After the process was proposed, international researchers and 6111 aluminum sheet manufacturers have a lot of research has been done. Haomei also used the ZWIKE100KN high temperature material testing machine for 6111 aluminum alloy to carry out thermal tensile tests on the material under different temperature ranges and strain rates to study the change law of material flow stress under high temperature conditions, and then obtain mechanical behavior of 6111 aluminum alloy in the rheological state in high temperature during the simultaneous quenching stage of hot stamping. So what did we find?

We use the 6111 aluminum sheets for sale with a thickness of 2mm as the test material, and use the ZWIKE100KN high temperature material testing machine to carry out the thermal tensile test of the material at 350~550 degrees Celsius and a strain rate of 0.1~10s. The results show that under the influence of dislocation density, the strain stress of 6111 aluminum alloy decreases with the increase of temperature, but increases with the increase of strain rate, which can be divided into two stages: strain hardening and saturated steady-state flow. The high temperature flow stress of 6111 aluminum sheet can be divided into two stages: strain hardening and saturated steady state flow. Under the same strain rate, the higher the temperature, the smaller the flow stress: when the temperature is constant, the greater the strain rate, the greater the flow stress.
