The focus was on exploring the welding parameters influence on joint properties, assessed through mechanical testing, metallography and hardness tests. Prolonged welding led to elevated temperatures, expanding the heat-affected zone, grain growth and microhardness at the interface. The temperatures effect on joint toughness was evaluated through Charpy impact testing at different temperatures, showing lower impact strength at −192 °C. Fracture surfaces exhibited increased micro voids and dimples as the temperatures decreased. The study highlighted a positive link between extended welding times and improved cryogenic impact strength and mechanical properties.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"138 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140078361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The composite powders were analysed by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and thermogravimetric-differential scanning calorimetry. Effects of cobalt modification on surface morphology, silver reduction rate, particle size and anti-oxidisation resistance of composite powders were studied. The results indicate that surface morphology of silver-coated copper powders prepared by cobalt-modified copper powders was affected by cobalt, but the size, mass and the percent reduction of silver were significantly increased under the same conditions of electroless plating silver. And silver-coated copper powders prepared by cobalt-modified copper powders have better anti-oxidisation resistance than silver-coated copper powders prepared by copper powders.","PeriodicalId":516293,"journal":{"name":"Materials Science and Technology","volume":"114 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140079172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that Fe3+ cations migrate towards octahedral sites with Ce doping. The optical band gap was decreased from 1.79 to 1.50 eV whereas saturation magnetisation was decreased from 57 to 49 emu/g with increase in Ce substitution. Maximum dielectric constant and minimum dielectric loss, maximum AC conductivity along with moderate magnetic properties were observed for x = 0.050.
