Abstract. In this work, a novel process of Cryogenic Treatment and Rapid Heating (CTRH) was proposed to decrease the residual stress and improve the properties of SiC-reinforced aluminum composite. An orthogonal test with parameters of cryogenic preserving time T(h), high-temperature medium (m), circulating times (N), and aging time t(h) was designed. The precipitates and residual stress were detected by TEM and XRD X-ray diffraction. The results show that the strengthening effect mainly comes from the finer and denser uniformly distributed needle-shaped θ'(Al2Cu) phase after CTRH. The process parameters optimized for low residual stress and high strength are T=36 h, circulating boiling water, N=2, and t=30 h.
