Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

Advanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Explosive Impact Crushing Characteristics of Magnetite Rock under Microwave Irradiation

工程科学与技术
为研究爆炸冲击荷载下微波辐照磁铁矿岩的宏观和微观破坏特征，本文对不同微波功率与时间辐照后的磁铁矿岩试样开展了爆炸冲击试验，通过筛分统计、分形维数计算和电镜扫描的方法，研究了相同冲击荷载下矿岩块度分布规律，并从微观角度阐述了矿岩破坏机制。结果表明：微波辐照使磁铁矿岩的温度升高是P波波速降低的主要因素。随着微波功率越高、辐照时间越长，微波总能量（功率×时间）相应增加，矿岩冲击破碎形态分别以片状块体（1.5 kW×1 min）、楔状碎块（3.0 kW×2 min）和柱状小碎块（4.5 kW×3 min）为主 ...
