The crack growth started from notch made on the deposit side and progress toward the substrate deposit interface under both loading conditions was monitored. The displacement rate in quasi-static loading and the loading rate for dynamic loading varied and crack propagation was studied. It was observed that the crack was deflected at the interface and not penetrated to the substrate, irrespective of loading conditions. The reason for crack deflection at the interface was analyzed using the energy-based method. It is shown that the ratio of fracture toughness of the interface to that of the substrate (0.044) is lower than the ratio of energy release rate for the deflecting crack to that of the penetrating crack (0.235). Thus, this material combination satisfies the condition for crack deflection rather than penetration. The fracture toughness of the interface was estimated as ~ 68 MPa m<sup>1/2</sup> and it falls between that of hardfacing alloy and SS316LN base metal. Optical and SEM examinations were conducted to corroborate the crack path deviations during crack growth. Results suggest that isolated cracks might be present on hardfaced coatings on critical components for which such cracks are usually not permitted. It may be allowed in preference to repair of these cracks, which is difficult and significantly increases the risk of additional cracks forming on the deposits because of the high susceptibility of the hardfacing alloy to cracking.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"33 23","pages":"13019 - 13029"},"PeriodicalIF":2.2,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-024-10389-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142789256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the slurry jet erosion test has performed on textured surfaces using a slurry erosion test rig. The hardness value of the various textured shape surface is higher than the others because mechanism of material removal for pattern is melting and evaporation, after applying an intense heat sudden cooling takes place. This might be altering the microstructure and enhances the hardness of the textured steel. The hardness value was the highest for circular-inward-textured case (HV0.3≈206) among all texturing. The tensile and flexural yield strength has marginally increased after texturing. The value of percentage elongation has marginally decreased after texturing. The modulus values for all the textured samples have enhanced as compared to untextured sample. Moreover, the modulus value of diamond-in textured samples are observed to be the highest i.e., ≈265GPa. The contact angles for all shapes of texturing patterns have greater values than untextured samples. All the textured surfaces show the hydrophobic and untextured surface as hydrophilic behavior. The outward textured surface has greater contact angle value (≈110°) as compared to others. The erosion resistance for the untextured samples have lesser among all textured samples, and the circular-in pattern has the highest erosion resistance.

Additionally, a marginal difference in the surface roughness of peened samples was observed for selected peening times.

The effect on the quality of the bond connections was investigated in setups with different load geometries, materials and load intensities. It was found that both wire damage due to cyclic mechanical alternating loading and a change in the interface between substrate and wire occurred. In the case of harder wire materials, complete breakage of the wire connections was observed after just 24 welds on terminals in typical geometries. However, the interface between the wire and the substrate was also damaged and lost 10% of its strength in this case. The investigations show how such effects can be minimized by the choice of wire material and geometry.

The present investigation aims to study the effect of quenching and partitioning times on RA stability, and the mechanical properties of 0.26C-1.87Mn-0.99Al-0.45Si steel subjected to hot rolling followed by direct quenching and partitioning (DQP). This present research introduces a new microstructural-based approach for identifying the optimal quenching and partitioning times to achieve a microstructure comprising of thin films of inter-lath austenite between martensite laths. DQP steels with longer quenching time exhibit blocky RA islands of smaller sizes. On the other hand, with a shorter quenching time, the microstructure contains a larger fraction of RA with higher carbon content, and this RA is predominantly film type along with small-sized blocky RA islands. This results in an excellent combination of mechanical properties (UTS of 1250 ± 39 MPa and % elongation to failure of 16%). The post-tensile microstructures were also examined using transmission electron microscopy, and film-type RA appears more resistant to strain-induced transformation.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"33 23","pages":"13311 - 13326"},"PeriodicalIF":2.2,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142789228","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}
