This work aims to optimize the process parameters for laser based DED manufacturing of a water jet impeller with critical requirements material and mechanical properties. The concerned is 2205 duplex stainless steel balanced ferrite-austenite microstructure. optimization approach processing relies on assessment their effect microstructure properties versus set by maritime industry. achieve an a...

Implantation using stainless steels (SS) is an example where an understanding of protein-induced metal release from SS is important when assessing potential toxicological risks. Here, the protein-induced metal release was investigated for austenitic (AISI 304, 310, and 316L), ferritic (AISI 430), and duplex (AISI 2205) grades in a phosphate buffered saline (PBS, pH 7.4) solution containing eith...

P. Vaňová, J. Sojka. VŠB Technical u niversity of O strava, FMME, Ostrava, Czech Republic This paper is dealing with hydrogen embrittlement of austenitic-ferritic 2205 duplex steel using the slow strain rate test (SSRT). The original material was subjec ted to heat treatment under 700 °C during 5 hours and f ollowing aircooling with the aim of pr ovoking sigma phase pr ecipitation and embrittle...

The temperatures and pressures influencing the formation mechanism of passive film corrosion products, as well passivation performance 2205 duplex stainless steel (DSS), were systematically studied via immersion tests, electrochemical measurements, various advanced surface techniques. results indicate that at 150 °C was an amorphous structure, while products comprised nano-polycrystalline FeCr2...

Mammalian sex determination hinges on the development of ovaries or testes, with testis fate being triggered by the expression of the transcription factor sex-determining region Y (Sry). Reduced or delayed Sry expression impairs testis development, highlighting the importance of its accurate spatiotemporal regulation and implying a potential role for SRY dysregulation in human intersex disorder...
