ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...

ABSTRACT An ultra‐high as‐deposited tensile strength of 1408 MPa—the highest reported value for laser‐directed energy deposition (L‐DED) fabricated Ti2AlNb alloy—is achieved in this study. The as‐deposited microstructure consists of coarse B2 grains with a high density of fine acicular O phase precipitates within the grains, along with a brittle α2 ...

Magnetization Dynamics Control for Noise Reduction in Fluxgate Sensors
ABSTRACT Fluxgate sensors are indispensable for the detection of weak magnetic fields. However, their noise performance remains constrained by an incomplete understanding of the interplay between the high‐frequency magnetization dynamics of the core material and the overall sensor behavior.

采用O3-H2O2工艺取代Fe/C-H2O2工艺对某农药厂废水进行预处理,对比研究了2种工艺对废水COD的处理效果,以及对后续生化处理的影响。结果表明,相比于Fe/C-H2O2工艺,O3-H2O2预处理对废水COD具有更好的处理效果,经O3-H2O2 和Fe/C-H2O2 预处理后,废水B/C 分别为0.64 和0.48。污泥镜检结果表明,废水经O3-H2O2工艺处理后,后续生化处理好氧池丝状菌生长量降低,从而抑制了污泥膨胀的产生。

ABSTRACT Precipitation of isothermal ω phase is an effective way to strengthen the metastable β‐Ti alloys but generally severely embrittles the materials by suppressing stress‐induced martensitic transformation and deformation twinning. Here, we architect heterogeneous structures with tailored ω phase in a metastable β‐Ti‐20Zr‐12Nb‐2Sn alloy via ...

Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy
ABSTRACT Niobium‐based refractory alloys are promising candidates for high‐temperature aerospace structures, yet their limited ambient‐temperature ductility and poor processability remain major barriers to broader implementation. Here, Nb521 alloy was fabricated by laser powder bed fusion (LPBF), and the effects of processing conditions and subsequent ...
