HfN dispersion enhances W-Re microhardness, compressive strength, and strain by 61.6 %, 59.7 %, and 28.4 %, respectively. Achieves 63% HfN particle dispersion within grains, enhancing fine-grain and coherent interface strengthening.

2019年1月1日 · Among sputtered nitridic films, hafnium nitride (HfN) offers a unique combination of properties by exhibiting a hardness of up to 32 GPa, a high chemical resistance against corrosive media, and an oxidation resistance in ambient air at …

米晶型HfN 粉体, 并研究了不同机械研磨速率和不 同气压下的反应动力学, 发现金属铪在转变为 c-HfN 前, 会形成间隙固溶体α-Hf; 小林秀彦等 [9] 使

2020年2月1日 · The HfN 2 monolayer possesses direct band gap (∼ 1.46 eV) and it is predicted to have high carrier mobilities (∼10 3 cm 2 ⋅V −1 ⋅s −1) from deformation potential theory. The direct band gap can be well maintained and flexibly modulated by applying an easily external strain under the strain conditions.

2025年3月13日 · Here, nitrogen-rich HfN films exhibit high hardness and metal-like ductility enabled by dislocation activity, attributed to a checkerboard superstructure ordering of metal vacancies and nitrogen...

2024年11月18日 · In this study, we employed a novel nitriding-decomposition process to synthesize W-10Re-HfN nano powder, in-situ synthesizing nano HfN particles to strengthen and toughen the W-Re alloy. Compared to W-10Re, the hardness of W-10Re-2HfN increased significantly from 604 HV to 977 HV, the compressive strength was …

2021年12月1日 · The thermoelectric properties of HfN 2 semiconductor have been calculated for its application in thermoelectric devices, while the scope for realizing a high-power conversion efficiency in 2D excitonic solar cells is explored by conjugating it with MoTe 2 monolayer. This work envisions a synergic combination of these two applications, where ...

The results show that intermediate product Hf 7 O 8 N 4 formed in the synthesis of HfN at high temperature in HfO 2-Si 3 N 4 binary system. Introduction of La 2 O 3 promoted the system to generate HfN which was beneficial to reduce the burning loss rate of ceramics.
