✦ Synopsis

Liquid metal induced embrittlement (LMIE) of En19 steel was investigated by tensile testing specimens coated with liquid pure tin. Testing was carried out over a range of steel hardnesses and test temperatures, and for each material hardness the temperature above which recovery of the unembrittled tensile behaviour of the specimens occurred was measured. Metallographic examination of each of the specimens was carried out and the results of this examination were compared with the mechanical behaviour. This work illustrates the importance of dissolution of the steel by tin on the behaviour of the specimens tested at the higher temperatures.
