Three different glass composites are fabricated by varying the weight% of CNPs. The hardness and tensile strength are found to increase by 2.65 times the primary glass with the addition of 0.4 weight% of CNPs. The homogeneous dispersion and close-packing of nanoparticles achieved in the resultant glass matrix account for this improvement. The closed-packed structure reduces the free volume between molecules, thereby limiting their movement and enhancing interfacial bonding. The formation of such a cross-linked structure with the addition of CNPs is supported by density measurements, electron microscopy images, and glass transition temperature studies.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"26 1","pages":"1835 - 1839"},"PeriodicalIF":1.8,"publicationDate":"2023-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86166775","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}

It is now being realised that MMCs can be formed in situ through the exploitation of rapid cooling rates of laser powder bed fusion, and targeting invariant reaction compositions to minimise the propensity for solidification cracking. We perform laser line scans and surface remelts of arc-melted Ti–0.38C, Ti–1.67B, Ti–8.5Si and Ti–32.5Fe wt-% eutectic compositions to assess potential material amenability to the laser powder bed fusion (LPBF) process at low cost as well as determining the nanostructure and hardness properties.

The results revealed that the relaxation rate increased dramatically as the temperature rose. The thermal stress relaxation resistance of Cu-15Ni-8Sn alloy was significantly improved with Co addition; After 100 h of stress relaxation tests at 200°C or 250°C, the residual stress value of the Cu-15Ni-8Sn alloy increased by 23 MPa or 22 MPa with Co addition, which was associated with the consumption of vacancies by Co atoms and the pinning effect of Co atoms on dislocation. However, at 250°C, the stress relaxation resistance of the Cu-15Ni-8Sn-0.2P alloy was lower than that of the Cu-15Ni-8Sn alloy. This difference was due to the inclusion of P, which promoted the recrystallization reaction. Article highlights Recrystallization and the decrease of dislocation density are the major reasons for the stress relaxation of the samples. The stress relaxation resistance of Cu-15Ni-8Sn alloy was significantly improved with Co addition. The addition of the P element is not conducive to the improvement of thermal stress relaxation resistance.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"10 1","pages":"1771 - 1781"},"PeriodicalIF":1.8,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73415573","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}

The results show that with the increase of tempering temperature, the microstructure of welded joint coarsens, the tensile strength and hardness decrease, and the toughness is improved.In the tempering process, M23C6 and Laves phases are produced in the welded joint. A certain amount of M23C6 precipitates can strengthen the mechanical properties of the welded joint. Excessive M23C6 carbides lead to the softening of martensite and the decrease of hardness; the formation of Laves phase can inhibit the excessive precipitation of M23C6, but the excessive precipitation of the Laves phase will lead to coarsening at the grain boundary and the formation of voids at the grain boundary.
