This means that the points at which different assembly and connection technologies are used are moving closer and closer together. This significantly increases the probability of mutual interference. The negative effects of later process steps in particular can be critical here. In the present work, a typical case for power electronics production is considered, consisting of thick-wire bonding on the power semiconductor and subsequent ultrasonic welding of load terminals on the same substrate. 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. This is another important building block in holistic process development, taking into account the interactions between different interconnection processes.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 6","pages":"4546 - 4554"},"PeriodicalIF":2.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-024-10313-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845691","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}

Hence, ensuring precise tailoring of RA content and morphology is crucial for Q&P steels. 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}

Optimal conditions were identified by the application of response surface methodology, leading to a significant decrease in mass loss. In material-specific reactions, HVOF-sprayed TiC showed increased resistance to cavitation because of its inherent micro-hardness (1293 HV). The reactivity of samples sprayed with PTFE varied, suggesting a complicated interplay between the properties of PTFE and jet velocities. SEM images verified the effectiveness of the PTFE and TiC coatings sprayed by HVOF as shields against corrosive elements. Even after seven cycles in a cyclic corrosion test, PTFE demonstrated outstanding corrosion resistance and impermeability, while the TiC coating created a dense, stable oxide layer. Furthermore, the combination of laser texturing and TiC and PTFE coatings sprayed with HVOF caused surfaces to exhibit superhydrophobic behavior (water contact angle: WCA > 155°). Extensive mechanical analyses provided information on surface roughness, bond strength, porosity, and microhardness, which helped to explain TiC's resilient resistance to indentation and strong adhesion (71.2 MPa) to the substrate. These findings offer practical methods and coatings to increase material resistance in conditions where cavitation and corrosive environments are common.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"33 23","pages":"12990 - 13003"},"PeriodicalIF":2.2,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142789219","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}
