Characterization of mechanical properties and microstructure of highly irradiated SS 316

Mechanics of the small punch test: a review and qualification of additive manufacturing materials

“…However, this required previous knowledge of the strain hardening exponent in order to be utilized, typically requiring tensile tests to characterize, thus rendering the ShPT redundant. Subsequent studies eliminated the need for previously established constants and proposed a more direct relationship [50,168,169]. This relationship can be expressed as…”

“…A database method for studying ductile materials involving the extensive use of FEA models generating theoretical materials to investigate actual specimens has also been proposed, with limited results showing good agreement for yield and ultimate strengths [184]. Additionally, Guduru et al and others have used correlation simulations to find correlation factors between the shear strength data produced using the shear punch test and tensile strength and yield strength [160,165,166,168,169].…”

Investigation of high temperature annealing effectiveness for recovery of radiation-induced structural changes and properties of 18Cr–10Ni–Ti austenitic stainless steels

“…Since the maximum swelling rate is implemented in the steady-state stage, recovery annealing should reduce the swelling to the lowest possible level e at least 2 orders of magnitude lower than the typical for the steady stage. Numerous studies show that the swelling on going to the steady- state stage is 1.5e2% [67,68]. At this for 18Cre10NieTi stainless steel incubation swelling period is 3e5 dpa [67,69e74] that is much less than the damaging dose after 60 years of VVER-1000 PVIs operation (120 dpa).…”
