The fatigue crack growth behavior of the newly developed GH4169 nickel-based alloy at a maximum stress of 700 MPa and different stress ratios was investigated in the present work employing the specimens with a single micro- notch at a frequency of 129 Hz at room temperature. The results demonstrate a typical three-stage process of fatigue crack propagation processing from the microstructurally small crack （MSC） stage to the physically small crack （PSC） stage, and finally to the long crack stage. The crack growth rate in the MSC stage is relatively high, while the crack growth rate in the PSC stage is relatively low. A linear function of crack-tip reversible plastic zone size was proposed to predict the crack growth rate, indicating an adequate prediction solution.

The survival of patients with hematological malignancies has been significantly improved due to the development of new therapeutic agents. However, relapse remains a major matter for concern. Recently, T cells engineered with chimeric antigen receptor(CAR) were reported to show unprecedented responses in a range of hematological malignancies. The persistence of the CAR-T cell can last for years and tends toward long-term antitumor memory by which relapses can be effectively prevented. The primary side effects that appear in most clinical trials are cytokine release syndrome and neurotoxicity. However, these symptoms can be treated and reversed. In this review, we describe CAR structure and function and summarize recent advances in CAR-T cell therapy in hematological malignancies.
