Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Titanium (Ti)–steel composite joints are prone to the formation of compounds such as TiC, TiFe, and TiFe2 during solid‐phase bonding. This phenomenon leads to premature failure and significantly reduces the bonding quality of the joints. However, the fracture behavior of the joint influenced by these compounds, particularly on the initiation ...

, 1990 采用宏观与微观相结合的方法,研究了不同种类不同部位的沿壁厚分层竹材的力学性能与生物组织微结构的关系。在扫描电镜内进行试验动态测试,并分析其形态。竹材主要由承力的纤维厚壁细胞和起速接作用并传递载荷的薄壁细胞基体所组成。竹材具有良好的比强度,比刚度,是其厚壁细胞竹纤维排列整齐的结果。在宏观力学性能方面;毛竹高于蒿竹,靠上部大于基部,竹壁外层优于内层,这都是与纤维组织细密、纤维层厚、纤维密度大等因素有关。对竹材生物组织微观结构合理分布和独突优越性的了解,不仅对竹材细胞组织的真实形态有进一步的科学认识 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Al‐based neutron shielding materials suffer from poor laser powder bed fusion (LPBF) processibility, hindering their simultaneous achievement of good printability and exceptional mechanical properties. In this work, the newly developed rare‐earth Al alloy (i.e., Al‐6Mg‐5Gd) was processed by LPBF technique to meet the printability, mechanical ...

Si Alloying Enables High Performance in Ce‐Substituted Hot‐Deformed Nd–Fe–B Magnets
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT High levels of Ce substitution typically degrade the magnetic performance of hot‐deformed Nd–Fe–B magnets, posing challenges for developing resource‐efficient permanent magnets. Here, we demonstrate that minor Si alloying in (Nd0.6Ce0.4)‐Fe‐B hot‐deformed magnets effectively compensates for this degradation and enables enhanced magnetic ...
