Rare Metals, Volume 45, Issue 8, August 2026.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 ...

热处理大豆球蛋白的体外消化稳定性In vitro digestion stability of soybean globulin after heating treatment
Zhongguo youzhi, 2022 为了有效评估大豆球蛋白抗原性变化，对热处理后的大豆球蛋白进行体外模拟消化实验，考察其体外消化稳定性。首先采用碱溶酸沉法从脱脂大豆粉中提取大豆球蛋白，然后将其经400 MPa超高静压处理15 min后进行加热（70、90、110、130 ℃）处理20 min，然后进行体外模拟消化实验，采用SDS-PAGE、邻苯二甲醛（OPA）法和间接竞争酶联免疫（ELISA）法研究消化过程中大豆球蛋白的蛋白质分子质量、水解度和抗原性的变化。结果表明：经体外模拟消化实验后，与未处理样品相比 ...

Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy
Rare Metals, Volume 45, Issue 8, August 2026.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 ...

Gongye shui chuli, 2018 选用芦苇为碳源，分析了经过简单处理、碱泡处理、碱热处理3种预处理方式后芦苇的静态释碳规律及其对反硝化的促进作用，在此基础上研究了碱热处理芦苇对人工湿地净化微污染水的促进作用。结果表明，碱预处理后的芦苇具有持续释放碳源的能力，进而能够持续强化系统的反硝化能力。在人工湿地系统中添加碱热处理的芦苇在不显著提高系统出水COD的前提下，显著提高了人工湿地的脱氮除磷能力，TN、TP平均去除率分别提高了39.36%、16.10%。

Dianci bileiqi, 2007 对未热处理及在不同温度下热处理的氧化锌电阻片进行了试验研究,结果表明,热处理可以提高8/20大电流冲击耐受能力,但工频过电压耐受性能有所降低;在保温时间一定的情况下,热处理温度在540～600℃之间,随着温度的提高,氧化锌电阻片耐大电流冲击性能也提高,而其工频过电压耐受时间减少;热处理温度在560～580℃时,氧化锌电阻片耐8/20大电流冲击和工频过电压耐受综合性能较好。将热处理和银电极还原同时进行也是一种较好的方案。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT The construction of core–shell grains can enhance the coercivity of Nd2Fe14B magnets. However, it is a significant challenge to elucidate the formation of these core–shell grains particularly regarding the spontaneous core–shell structure in Y‐substituted Nd2Fe14B alloys.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

Dianci bileiqi, 2005 采取提高热处理温度、延长保温时间等措施,改善直径大且厚的电阻片老化性能,取得了较好的效果。试验证明,热处理工艺可使电阻片的压比明显降低;在0.75U1mA下的阻性电流除少数外均有不同程度的增大,总的规律是尺寸大的比小的增大得多;热处理可明显提高电阻片的方波通流能力,并改善其稳定性。欲通过热处理使电阻片的性能获得最佳,必须根据电阻片的尺寸、烧成制度等调试热处理炉的温度制度及装片密度,选定较合理的工艺。采用再次热处理的方法使已抽查试验的电阻片性能得到恢复。通过X衍射试验 ...
