Fig. 572 Four fracture surfaces of a hemispherical accumulator head of high-strength low-alloy steel (0.15% C, 0.8% Mn, 0.6% Cr, and 0.85% Ni) that broke into several pieces during pressure testing at room temperature. Hardness ranged from 28 to 39 HRC. Fracture originated at a thin spot More

Fig. 6 Both sides of the fracture surface from a failed steam accumulator. Section of the vessel is the upper piece, and the mating head is the lower piece. More

Fig. 7 Several sections through a girth weld in a field steam accumulator showing lack of weld penetration. More

Fig. 2 Reciprocating-screw accumulator. (a) Screw turns to melt material and accumulate it in front of the screw tip and then is moved back from the pressure of the plastic melt. (b) Screw moves forward to force material through, forming parison. More

Fig. 23 Both sides of fracture surface from a failed steam accumulator. Section of the vessel is the upper piece, and the mating head is the lower piece More

Fig. 7 Illustration of ratcheting leading to continued plastic strain accumulation More

Fig. 27 Stress accumulated during cooling under restraint for selected steels. The dotted line shows the expected variation in stress for a duplex austenite-martensite weld metal where transformation below about 100 °C (212 °F) greatly reduces the final stress. (MMA 1320 indicates the peak More

Fig. 11 (a) Accumulative release of vitamin D 3 from 30 wt% NaP and 350 μm 3D printed (3DP) in pH 7.4. (b) Osteoblast cell morphology of the scaffolds with MTT assay at day 11. White arrows: cells; black arrows: covered cells in 3DP samples. VD3, vitamin D 3 ; PCL, polycaprolactone; PEG More

Fig. 5 Effects of water accumulation in the sump area of a black box. The arrow points to the high-voltage lead wire that has completely corroded, rendering the unit nonfunctional. Note that the connector is wrongly positioned horizontally inside the box. More
