To study the compatibility especially the corrosion characteristic of structural material stainless steel (SS) with liquid lithium (Li) is an important factor for the simultaneous application of liquid Li and SS as a blanket material or potential plasma facing material (PFM) in future fusion devices. The corrosion behaviors of 304SS exposed to liquid Li at 700 K for 1320 hr under high vacuum were investigated. After exposure to liquid Li, 304SS produces non-uniform corrosion which includes corrosion products and grain boundary corrosion. Compared with the corrosion behaviors at 600 K and 640 K, temperature plays an important role in the corrosion behaviors of 304SS in static liquid Li. The weight loss, corrosion depth and corrosion products of 304SS specimens increase with the corrosion temperature. In general, the compatibility between 304SS and static liquid Li is relatively good under the experimental conditions. And besides, it is unexpectedly found that the compatibility of copper with Li is not good.

研究相容性尤其是结构材料不锈钢（SS）与液态锂（Li）的腐蚀特性是在将来的熔合中同时应用液态Li和SS作为覆盖材料或潜在的面向等离子体的材料（PFM）的重要因素设备。研究了高真空下700SS暴露于700 K液态Li 1320 hr的304SS的腐蚀行为。暴露于液态锂中后，304SS会产生不均匀腐蚀，包括腐蚀产物和晶界腐蚀。与在600 K和640 K下的腐蚀行为相比，温度在304SS在静态液态Li中的腐蚀行为中起着重要作用。304SS试样的失重，腐蚀深度和腐蚀产物随腐蚀温度的增加而增加。一般来说，在实验条件下，304SS与静态液态锂的相容性较好。此外，出乎意料地发现铜与Li的相容性不好。
