Selective Laser Melting (SLM) shows a big potential among metal additive manufacturing (AM) technologies. However, the large thermal gradients and the local melting and solidification processes of SLM result in the presence of a significant amount of residual stresses in the as built parts. These internal stresses will not only affect mechanical properties, but also increase the risk of Stress Corrosion Cracking (SCC). A twister used in an air extraction pump of a condenser to create a swirl in the water, was chosen as a candidate component to be produced by SLM in 316 L stainless steel. Since the main expected damage mechanism of this component in service is corrosion, corrosion tests were carried out on an as-built twister as well as on heat treated components. It was shown that a low temperature heat treatment at 450℃ had only a limited effect on the residual stress reduction and concomitant corrosion properties, while the internal stresses were significantly reduced when a high temperature heat treatment at 950℃ was applied. Furthermore, a specific stress corrosion sensitivity test proved to be a useful tool to evaluate the internal stress distribution in a specific component.

The Maksyutov complex is a part of Precambrian folded belt extending from Urals, North Karakum, Kunlun, Qilian, Qinling to the Dabie-Sulu belt of eastern China. In Maksyutov the eclogites present as individual blocks and boudines embedded within the glaucophane and micaceous schists. Due to the Phanerozoic multi-phase granite intrusions and their resulting superposed metamorphism the data on the age of eclogite are diverse spanning from Early Proterozoic to lower Paleozoic. The mineral compositions of the eclogite are constant with garnet, omphacite and rutile; however, they are often replaced by metamorphic assemblages of epidote-blueschist facies. The garnets are iron rich with f=50-75 % (f = Fe2+/(Mg + Fe2+)). Clinopyroxenes are omphacites with Jd 40.3-52.2. According to the garnet-clinopyroxene geothermometry and Jadeite + quartz→albite geobarometry T=1060-686℃, P=2.23-1.416 GPa are estimated. The PT trajectory of Maksyutov eclogite corresponds to the upward intrusion of eclogite magma, the final consolidation of the eclogites probably took place in the lower crust.
