We found that the generated oxides in the interface became spherical and dispersed, which was caused by selective oxidation due to the reduced oxygen partial pressure during high welding temperature. Then, these oxides were further refined and dispersed by severe material flow around the welding interface. Consequently, the refined and spherical (Mn, Si, Al)O amorphous oxides were formed. In addition, strong material flow introduced large drive force for grain boundary migration around the welding interface, which further facilitated the migration and dispersion of the generated (Mn, Si, Al)O oxides, giving rise to a high-strength welding interface.","PeriodicalId":21729,"journal":{"name":"Science and Technology of Welding and Joining","volume":"28 1","pages":"182 - 192"},"PeriodicalIF":3.3,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45053347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present work investigates the effect of applying in-situ electric pulses to the component after the deposition of every layer to reduce residual stresses. The experimental results revealed that electropulsing resulted in dislocation rearrangement/annihilation, thereby decreasing dislocation density. A significant reduction in the fraction of low angle grain boundaries was observed for electropulse-treated samples, indicating a decrease in residual stress. Further, X-ray diffraction results also confirm a reduction in residual stress (24.0–29.4% reduction compared to untreated samples). The method can effectively be used to address specific regions selectively in addition to in-situ reduction of residual stresses in deposited components.

A novel method called ‘double-sided friction stir welding’ solved this problem by weakening the texture. However, the texture-weakening mechanism remains unclear. In this study, the mechanism of the texture weakening in double-sided friction stir welded Mg alloy was systematically analysed. The welding temperature and the material flow mode were revealed to control the (0001) texture randomisation simultaneously. The unique material flow at the mid-thickness layer caused by the double-sided friction stir welding was revealed to match the ‘beat phenomenon’ for the first time, which was revealed as the dominant mechanism for the (0001) texture randomisation.","PeriodicalId":21729,"journal":{"name":"Science and Technology of Welding and Joining","volume":"28 1","pages":"154 - 161"},"PeriodicalIF":3.3,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47504966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a microstructure and mechanical property gradient not only along the welding direction, but also perpendicular to it.

Stable descending flow is a key to suppressing the contamination, which affects the particle ascending velocity, horizontal deflection of particles and number of residual particles. The laser transmission area can be protected using a gas flow rate of 1.0 L min−1 or a cone height of 90 mm for the conical component.
