Abstract
This study elucidates the microstructures and mechanical properties of a 30CrNi2MoV steel/GH4098 joint produced via hot-compression bonding (HCB). Owing to the mutual diffusion of GH4098 and 30CrNi2MoV, the bonding interface becomes an interface band where Al2O3/Ti(C, N) is distributed on the side near GH4098 and Ti(C, N)/M23C6 is distributed on the side near 30CrNi2MoV. A transition layer occurs between the interface band and 30CrNi2MoV due to the diffusion of austenite stabilization elements dominated by Ni from GH4098 to 30CrNi2MoV. As the hot compression temperature increases, oxides and carbides are thermally dissolved into the matrix and Al2O3 transitions from its δ phase to α phase. As the strain increases, the bonding interface bugles and the interfacial oxide layer is destroyed. The highest interfacial bonding strength is obtained under conditions associated with high temperatures and large deformation.
期刊介绍：
Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry.
The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
