Generation and Relaxation of Residual Stresses in Automotive Cylinder Blocks
[chapter]
2020
Automotive System Engineering - New Methods and Optimal Solutions [Working Title]
There is direct proportionality between ultimate tensile stress (UTS) and residual stresses (RS). Residual stresses gradually decrease with decreasing cooling/quenching rates. Quenching in cold water develops highest, whereas air cooling produces lowest, residual stresses. Significant increase in RS is observed in specimens with low dendrite arm spacing (high solidification rate), while lower residual stresses are measured in specimens with high dendrite arm spacing (low solidification rate).
