Strain-aging processes have shown potential to increase yield strength while mitigating the exhaustion of work hardening, facilitating the combination of ultra-high yield strength and exceptional ductility in Transformation-Induced Plasticity (TRIP)-assisted steels. However, the underlying mechanisms of Lüders band formation and its quantitative relationship with the TRIP effect in steels with a yield strength above 2 GPa remain to be fully elucidated. In this study, we prepared an easily formable initial medium Mn steel with martensite/austenite microstructure through low-cost composition design and a simplified process (hot rolling + tempering). The strain aging process endows this steel with a yield strength as high as 2294 MPa and a uniform elongation exceeding 10 %. The results demonstrate that with the increase in pre-strain, some block austenite gradually transforms into fresh martensite and high-density of dislocation can be obtained, which leads to a very high bake hardening response of 531–569 MPa, making significant contributions to the enhancement of yield strength. The strain mechanism of Lüders band is analyzed by digital image correlation method (DIC). When the pre-strain increases from 3 % to 4 %, the strain value of Lüders band increase, and the austenite fraction in the strain interval of Lüders zone changes little, which indicates that there is little TRIP effect in Lüders band deformation. At the same time, a large amount of austenite performs TRIP effect in the hardening stage after Lüders band deformation, which provides enough work hardening and obtains a very high uniform elongation of about 10 % at 2.3 GPa. The main mechanism in Lüders zone strain is dislocation slip, accompanied by dislocation multiplication behavior.</div></div>","PeriodicalId":385,"journal":{"name":"Materials Science and Engineering: A","volume":"930 ","pages":"Article 148172"},"PeriodicalIF":6.1,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adding aluminum to induce NiAl precipitation can increase the strength but the toughness is reduced. Therefore, it remains a challenge to keep decent toughness through NiAl and M₂C dual precipitation when reducing Co content. Here, double ageing is proposed in a low-cost UHSSs to achieve good combination of strength and toughness through dual-precipitation control and austenite modification. Ageing at 482 °C for 32 h followed by ageing at 600 °C for 20 min (DA482 + 600) exhibits a smaller size of M₂C carbide and a smaller number density of NiAl particle than that ageing at 600 °C for 20 min followed by ageing at 482 °C for 32 h (DA600 + 482). Additionally, the DA482 + 600 sample obtains a larger volume fraction of film reversed austenite and a smaller size of blocky reversed austenite. These make it have higher impact toughness. Although the precipitation strengthening for NiAl particles and M₂C carbides is different in two samples, when considering the interaction during dislocation movement through these precipitates, Pythagorean addition rule indicates that the total precipitation strengthening is similar. Additionally, the course of heat treatment is the same and, in turn, the solid solution, dislocation density and width of martensitic laths are comparable, leading to similar strengthening contributions. As a result, the yield strength remains comparable high. When comparing strength-toughness and raw materials cost with representative secondary hardening UHSSs, the DA482 + 600 sample exhibits superior combination.</div></div>","PeriodicalId":385,"journal":{"name":"Materials Science and Engineering: A","volume":"931 ","pages":"Article 148159"},"PeriodicalIF":6.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a dual heterostructured Ni-Co-based superalloy characterized by harmonic grain heterostructure comprising fine grains and ultrafine grains, which is accompanied by bimodal-sized γ′ precipitates. The superalloy exhibits an outstanding strength-ductility synergy, with high yield strength (∼1.5 GPa) and ultimate tensile strength (∼1.8 GPa), concurrent with high uniform elongation (∼21 %), which is much higher than its solution and aging counterparts and superior to most superalloys. The excellent tensile properties primarily originate from its distinctive heterostructure and work hardening mechanism. The inhomogeneous plastic deformation leads to a high density of geometrically necessary dislocations pile-up near the hetero-zone boundaries, yielding so-called hetero-deformation-induced hardening. Besides, the bimodal-sized γ′ precipitates effectively impede dislocations slip to improve work hardening capacity.
