摘要 ：
基于薄板激光焊失稳数值分析理论,建立了矩形栅格结构的激光点焊仿真模型,通过提取超薄板十字交叉结构激光点焊后固有应变的分布,在栅格结构面外失稳变形模型中计算得到十字交叉接头第一阶正特征值屈曲模态,表现为偏转变形.随着热输入的增大,接头的面外变形量明显增加,且偏转方向改变.对两种焊接顺序下的栅格结构进行特征值屈曲变形分析,发现焊接顺序1条件下第1层薄板接头处有明显的向下偏移,变形挠度为27μm.焊接顺序2下薄板的屈曲特征值较小,此时薄板的整体挠度增大.焊点个数的增多导致失稳变形更容易发生,具体表现为薄板的屈曲特征值持续下降,焊点附近屈曲变形的相互耦合作用会使栅格结构在中间层的面外变形量相比顶部和底部区域有明显增大.

摘要 ：
The 410 stainless steel (SS410) large-size block part without defects was successfully prepared by cold metal transfer (CMT) wire-arc additive manufacturing (WAAM). Results showed that 5-ferrite in SS410 could be eliminated during deposition without any extra post-treatment. The content of martensite in the central zone and overlap zone both exceeded 96%, and the rest was punctate austenite. The average strength/elongation of the as-deposited (AD) block part was 1323 MPa/4.1%. By comparing the tensile properties of AD samples with low-temperature annealing (LA), full annealing (FA), and high temperature tempering (HT) post-heat-treated samples, the HT could achieve the best balance of strength and ductility with an elongation about 12.7%. This work proved that the high-performance parts could be prepared through WAAM by using appropriate processing parameters. (C) 2021 Published by Elsevier B.V.

摘要 ：
Because large plastic deformation occurs in hydroforming bellows there is a residual stress distributing in the metal after forming, which is complex and not easy to be measured. The existence of residual stress might have an effect on the corrosive property and bulking performance of bellows. A finite element model was established to simulate the forming residual stress of the nickel alloy multi-layer bellow. The distribution of residual stress was calculated out and validated by cos alpha X-ray diffraction measurement. Thus the forming mechanics and the effects of layer number and forming pressure on the residual stress in the hydroforming bellow were both discussed in detail based on the established model. It was shown that the calculated residual stress had the same trend with the experimental results. The axial and circumferential residual stresses at the outer surface of the peak were both compressive. There existed the maximal Von Mises stress at the inner surface of the peak of the bellow. At this position the radial and axial residual stresses were both tensile. When applying multi-layer bellows and less forming pressure a lower forming residual stress could be obtained because of the narrow plastic strain region during forming.

摘要 ：
2Cr13 thin-wall part was additively deposited by robotic cold metal transfer (CMT) tech-nology, and two traditionally manufactured counterparts in annealing (as-Aed) and quenching & tempering (as-QTed) conditions were adopted as comparison. The results show that only a strong texturing corresponding to alpha-Fe phase was detected for the wire-arc additively manufactured (WAAM) part, indicating an austenite-free structure. As-deposited microstructure was consisted of martensite laths and ferrite matrix, along with irregular delta-ferrite precipitation. The martensitic growth direction was non-oriented in the X-Y plane, but primarily parallel to the depositing direction in the X-Z and Y-Z planes along the maximum thermal gradient. Both nanohardness and ultimate tensile strength (UTS) for each WAAM sample were enhanced when compared with the as-Aed BM, while poorer than that of the as-QTed BM. Such mechanical evolution was a result of the intrinsic micro-structural features, whereas the similar elastic modulus properties were mainly attributed to the similar 2Cr13 atomic bonding. A ductile tensile fracture behavior was dominant in the X-Z plane, while a mixed mode of ductile and brittle fracture occurred in the X-Y and Y-Z planes. The findings above reveal an isotropy in mechanical properties despite a slightly microstructural discrepancy in different planes for the as-deposited 2Cr13 WAAM part. (C) 2021 The Authors.

摘要 ：
In this work, H13 buildups were produced through wire-arc additive manufacturing based on cold metal transfer technology. Four different deposition strategies were employed for the fabrication and the microstructural evolution and mechanical properties of the corresponding buildups were compared. A bimodal microstructure for all buildups produced in the overlap zone (OZ) and body zone (BZ), respectively, despite a mixture of lath-shaped martensites and blocky delta-ferrites in the OZ and a slightly coarser but still fine martensites in the BZ. The as-deposited mechanical properties were evidently superior to the properties of the base metal after annealing, but slightly inferior to that after quenching and tempering. Compared with the components with different deposition patterns between adjacent layers, the relatively enhanced hardness and wear-resistance properties were acquired for the ones with the same scanning strategies, being responsible for the smaller retained delta-ferrite size in the OZ and slightly refined martensites in the BZ. The deposition strategy had a negligible influence on the wear surface hardness, all decreasing gradually from the wear zone to the transient zone and finally keeping stable as a result of the locally martensitic evolution. As the in-situ thermal history was influenced by the deposition strategies, both of the microstructural distribution and mechanical performances were affected by the deposition strategies. Besides, the applied strategies, characterized by the different scanning directions between adjacent tracks, had a negligible influence on microstructures and mechanical properties following comparison with the counterparts with the different directions between adjacent layers.
