To support complex multi-metal structures, a variety of techniques are required to join dissimilar metal parts with precise shapes. This study evaluates vacuum diffusion bonding as a method for joining titanium and vanadium, focusing on both pure titanium and the common alloy Ti-6Al-4V. We employ modest pressure provided by a weight and simple surface preparation to simulate the most commercially applicable process. We show that Ti-6Al-4V alloy bonds readily to V, forming a continuous, clearly defined interdiffusion layer with predictable kinetics. Conversely, commercially pure Ti forms a crack-prone bond with V that fails to improve at higher bonding temperatures or longer times. We attribute this failure to the concentration of stress caused by the ß-to-α phase transformation in Ti. The contrasting bonding efficacy between pure Ti and the alloy provides insight into the crystallographic interactions that occur at the interface during bonding and cooling. These results provide surprising insight into a new method for bonding Ti alloys to V and possibly other metals that share the body-centered cubic crystal structure.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 3","pages":"2579 - 2590"},"PeriodicalIF":2.3,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147338774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A modified Page model was applied to fit experimental data from the drying process, and the results demonstrated an excellent model fit, enabling accurate prediction of moisture changes in coal slurry under varying conditions.

By contrast, oxygen enrichment during cooling or throughout the process increased perovskite (CaTiO3), produced skeletal hematite (Fe2O3), and induced microcracking and porosity, thereby weakening the bonding phase and worsening RDI.

The wear surface showed abrasive wear and slight adhesive wear.

This study fabricates tungsten carbide (WC)/Stellite 6 composite coatings on high-chromium cast iron BTMCr20 using circular oscillating laser cladding to examine the effects of WC content (0–30 wt.%) on the microstructure and mechanical properties. Results indicate that laser oscillation induces mechanical stirring that enhances molten pool convection, effectively inhibiting WC particle settling and maintaining uniform distribution even at 30 wt.% WC. In addition to the inherent grain refinement effect of the oscillating laser, the increasing WC content provides additional heterogeneous nucleation sites, leading to further microstructural refinement. This resulted in a reduction of the average grain size by approximately 40% compared to the coating without WC, which is attributed to the presence of reinforcing phases such as W2C, Fe7W6, and Cr7C3. Microhardness and wear resistance improve linearly with WC content, reaching 613 HV0.2 and 2.17 × 10−4 mm3 wear volume at 30 wt.% WC. The wear mechanism transitions from mixed abrasive-adhesive to predominantly abrasive wear.
