“…For this purpose, fast cooling rates are required to avoid or limit precipitation during the quenching process [2]. However, high cooling rates result in serious inhomogeneous deformations and lead to high residual stresses [3], which deteriorates the mechanical properties and dimensional stability [4,5], and also have important impact on fatigue properties [6][7][8]. Therefore, it is important to study how to control the residual stresses.…”

“…Many researchers employed vibration methods to release the residual stresses [11,12] and studied their mechanisms [13]. However, this technique is confined to large components since the high amplitude of vibration deforms the thinner or smaller components [5]. Heat treatment methods are also applied to relieve the residual stresses.…”

Abstract:To lessen quenching residual stresses in aluminum alloy components, theory analysis, quenching experiments, and numerical simulation were applied to investigate the influence of temperature-dependent material properties on the evolution of plastic strain and stress in the forged 2A14 aluminum alloy components during quenching process. The results show that the thermal expansion coefficients, yield strengths, and elastic moduli played key roles in determining the magnitude of plastic strains. To produce a certain plastic strain, the temperature difference increased with decreasing temperature. It means that the cooling rates at high temperatures play an important role in determining residual stresses. Only reducing the cooling rate at low temperatures does not reduce residual stresses. An optimized quenching process can minimize the residual stresses and guarantee superior mechanical properties. In the quenching process, the cooling rates were low at temperatures above 450 • C and were high at temperatures below 400 • C.

“…[11][12][13] The TSR belongs to the conditional stress relieving technology compared with the VSR, in which the treated workpiece was placed in the annealing furnace to be heated up to the annealing temperature. Meanwhile, the treated workpiece need to hold definite times at the annealing temperature followed by a desired rate of cooling.…”

The high-energy oscillating electric current pulse (ECP) technology was introduced to relieve the residual stresses in the small AISI 1045 steel specimens treated by the pulsed-laser surface irradiation. The high-energy oscillating ECP stress relief experiments were conducted to study the effectiveness of the high-energy oscillating ECP technology. In addition, the electroplasticity framework was developed based on the thermal activation theory to reveal the mechanism of the high-energy oscillating ECP stress relief. The results show that the high-energy oscillating ECP stress relief has good effects on eliminating the residual stress. Furthermore, the residual stress relieving mechanism of the high-energy oscillating ECP stress relief can be attributed to the electric softening effect and the dynamic stress effect. The findings confirm that the significant effects of high-energy oscillating ECP on metal plasticity and provide a basis to understand the underlying mechanism of the high-energy oscillating ECP stress relief.

The microstructure evolutions and mechanical properties of in‐situ TiB2/7050 Al composites with a set of pre‐strains are investigated. This study shows that most quenched‐in residual stress can be removed by ≥1% pre‐strain. Meanwhile, the coupling of pre‐strain and TiB2 particles within grains has a profound impact on mechanical properties of composites treated by the artificial aging. The yield strength increases with the increasing pre‐strain, i.e., the yield strength increases from 669 MPa to 697 MPa through 5% pre‐strain. Analytically, the pre‐strain is beneficial to the dislocation strengthening, but harmful to the precipitate strengthening during the aging process. Nevertheless, TiB2 particles are beneficial to both dislocation strengthening and precipitate strengthening in the aging duration. As a result, the improvement in dislocation strengthening is found larger than the loss in precipitate strengthening, leading to the increment in yield strengths of artificial aged composites. The underlying mechanisms are discussed on the basis of quantitative theoretical analysis of diffusion‐controlled precipitation in combination with multi‐scale microstructure characterizations (i.e., scanning electron microscope, transmission electron microscope, small‐angle X‐ray scattering and X‐ray diffraction).
