  • When do microscale residual stresses begin to develop?

    In general, microscale residual stresses develop after material processing and subsequently evolve under applied loading. Following the literature 8, we use the terms residual stress and internal stress interchangeably with regard to these microscale residual stresses.See all results for this questionWhat can residual stresses do to a part?Significant residual stresses [34] can thus exist in additively manufactured part. Apart from their detrimental influence on mechanical performance, residual stresses could give rise to part distortion and dimensional inaccuracy [35], [36], [37], [38].See all results for this questionWhat are residual stresses in additively manufactured materials?Residual stress is one of the most critical issues for additively manufactured (AM) metallic materials 1, 2, 3, 4, 5. Its presence can influence the mechanical behaviour of AM parts. This issue is especially significant for AM materials processed by selective laser melting (SLM), which inevitably results in substantial residual stresses.See all results for this question

Comparing the volume changes during phase transformations it is clear that the microstructure having the highest residual stress, due to volume change and dislocation density, is martensite. Tempering of martensite resulted in an increase in the sound velocity.How are residual stresses distributed in polycrystalline materials?The residual stresses in polycrystalline materials can be categorized according to two major classes: 6, 7 macroscale and microscale residual stresses. The so-called Type I macroscale residual stresses are distributed across the overall dimension of a part and contribute to its distortion.See all results for this question
