Hydrogen embrittlement induced fracture of 17-4 PH stainless steel valve stem
2020, Engineering Failure AnalysisCitation Excerpt :High-strength steels are more susceptible to environmentally assisted cracking. Previous studies showed that inappropriate heat treatment may cause hydrogen embrittlement (HE) and stress corrosion cracking (SCC) [14,15]. Tavares et al. [16] investigated two failures of springs on pressure safety valve (PSV).
Tandem metal inert gas process for high productivity wire arc additive manufacturing in stainless steel
2019, Additive ManufacturingCitation Excerpt :Instead, the difference between the specimens built with WFS = 8 m/min and WFS = 9 m/min is statistically significant (p-value = 0.0192). The hardness test results using a tandem troch pulse MIG welding with a lowest deposition rate of 4.5 kg was seen to be around 398 HV [10]. The results obtained for higher deposition rates are close to the single CMT process from the past study, which at much lower deposition rate achieved a hardness of 340 HV.
