The stress-strain curves of iron based alloys deformed over a wide temperature range exhibit a serrated flow associated with the Portevin-LeChatelier (PLC) effect. Properties of materials in general depend not only on the test temperature but also on the test environment. The effect of test atmosphere on mechanical properties of intermetallics has been recently confirmed. From that point of view it should be pointed out that most of the studies in the past on PLC effect were carried out in standard air atmosphere. In the present study the combined effect of temperature and test atmosphere on the mechanical properties of 316L in the range of serrated flow was investigated. Two basic test conditions were employed: straining in air and vacuum.
