Bimetallic transition joints using aluminum alloy 6061-T6 and stainless steel 304 L are useful in providing reliable stainless steel welds on nuclear components at temperatures below 200 °C, while maintaining the attractive radiation tolerance of the aluminum alloy. The mechanical performance of inertia welded Al6061-T6:304LSS transition joints was evaluated after neutron irradiation up to 3.45 dpa at 100 °C (maximum) in the High Flux Isotope Reactor to determine the viability of using these transition joints for nuclear and reactor applications. Neutron radiation produced moderate hardening (Δσ_y$\approx$90 MPa) with limited change in ductility. Tensile specimens were produced from multiple transition joints and no batch-to-batch variation was found. Tensile responses were found to align with typical responses of wrought Al6061-T6, indicating that the behavior of the joints was dictated by the Al6061-T6 section of the joint.

使用铝合金6061-T6和不锈钢304 L的双金属过渡接头可用于在温度低于200°C的情况下在核组件上提供可靠的不锈钢焊接，同时保持铝合金的抗辐射公差。在中子在高通量同位素反应堆中于100°C（最大）辐照高达3.45 dpa后，评估了惯性焊接Al6061-T6：304LSS过渡接头的机械性能，以确定将这些过渡接头用于核反应堆应用的可行性。中子辐射产生中度硬化（Δσ _ÿ$\approx$90 MPa）的延展性变化有限。拉伸试样是由多个过渡缝制成的，没有发现批次间的差异。发现拉伸响应与变形的Al6061-T6的典型响应一致，表明接头的行为由接头的Al6061-T6截面决定。
