The invention discloses a shape control method for a spaceflight 2195 aluminum alloy frame beam piece. The shape control method comprises the following steps: carrying out vacuum gas quenching on an annular part; performing subzero treatment and uphill quenching treatment on the annular part subjected to vacuum gas quenching; and carrying out harmonic vibration aging treatment on the annular part subjected to liquid helium subzero treatment, and cooling to obtain the frame beam part. The invention further discloses the frame beam piece obtained through the control method. According to the method, the residual stress of the spaceflight 2195 aluminum alloy frame beam piece can be reduced, uniform stress distribution is achieved, quadratic term precipitation and grain refinement are promoted, and the mechanical property of the component is improved.

    本发明公开了一种航天2195铝合金框梁件形性控制方法,包括对环形零件进行真空气淬;对真空气淬后的环形零件进行深冷处理和上坡淬火处理;对液氦深冷处理后的环形零件进行谐波振动时效处理,冷却后得到框梁件。本发明还公开了一种利用上述控制方法得到的框梁件。本发明能够降低航天2195铝合金框梁件框梁件残余应力,实现应力均匀分布,促进二次项析出和晶粒细化,提升构件力学性能。
