Microstructure observation shows that with increasing upset pressure, grain refining effect of plastic deformation overrides grain growth effect of heat input, leading to finer prior austenite grains on AISI 4140 side. Dendritic structure of IN713LC transformed into fine equiaxed grains. Weld joints fabricated using low upset pressure showed unbonded regions with curved shape profile. However, weld joints made using high upset pressure showed nearly straight-line joint profile and was found to be favourable for adequate plastic deformation and achieving better bonding. Improvement in mechanical properties of weld joint was observed with increasing upset pressure.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141924246","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 research findings demonstrated that with the addition of accelerator, a large amount of hydration products is formed in the paste. The dosage of PAH was 2%, the strength of the mortar reached 13.96 MPa at 1 d. The primary cause is that the PAH formed a granule-particle bridge structure, which made the structure of hydration products denser, thus improving the early compressive strength.

The as-received (AR) materials were exposed at different temperatures for a fixed duration and subsequently thoroughly characterized by employing several techniques suitable for microstructural and mechanical property evaluations. It was interesting to notice that both the amount of retained austenite as well as its C concentration were decreasing with higher temperature making it more unstable which could be reflected from the decreasing trend in the value of true strain that indicates the point of instability. It was observed that the dislocation annihilation coefficient ( k2) was increased while the corresponding storage coefficient ( k1) did not change much with the increase in exposure temperature compared to the AR sample.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141922093","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}
