2020年10月12日 · NTN has applied newly developed heat treatment process (ETFA treatment) on the carburized steel, and confirmed that the newly developed “ETFA Bearing” has the operating life 6 times longer or more than that of standard product and 2 times longer than that of “ETA Bearings” under debris-contaminated conditions.

2020年10月12日 · NTN has applied newly developed heat treatment process (ETFA treatment) on the carburized steel, and confirmed that the newly developed 'ETFA Bearing' has the operating life 6 times longer or more than that of standard product and 2 times longer than that of 'ETA Bearings' under debris-contaminated conditions.

2020年10月8日 · このたび開発した「etfa軸受」は、浸炭鋼に新たな熱処理(etfa処理)を施すことで、異物混入潤滑条件下で、標準品と比べ6倍以上、eta軸受と比べても2倍以上の寿命を持つことを確認しています。

2022年2月9日 · To identify the phase transformation mechanism from austenite (γ) to martensite (α′), we used an X-ray free-electron laser and ultrafast heating and cooling techniques.

2023年6月21日 · Meanwhile, introducing proper cosolvents is also feasible to improve the ionic conductivity at low temperature. As a typical example, ethyl trifluoroacetate (ETFA), identified as a weakly solvated solvent, has been found to facilitate the desolvation process as shown in …

2024年9月26日 · These outcomes offer clear insights able to optimize industrial heat treatment parameters, with strong implications regarding steel bearings’ products. Merlin et al. (Contribution n.2) focuses on post-fabrication heat treatment (PFHT) as a tool aimed to target microstructure and mechanical properties of components produced by additive ...

2023年3月1日 · Post-processing heat treatment is often needed to modify the microstructure and/or alleviate residual stresses to achieve properties comparable or superior to those of the conventionally manufactured (CM) counterparts.

A heat treatment furnace is a specialised piece of equipment used to carry out heat treatment, with the ability to control the heating and cooling of workpieces. Heat treatment is a type of process that improves quality by heating and cooling workpieces and can change the internal properties of the material without changing its shape.

三氟乙酸乙酯(etfa)作为一种重要的有机化工原料，在合成有机氟化合物、医药、农药、液晶及染料等行业有着广泛的应用；具体应用如下： (1)在医药方面上，主要应用于生产骨关节炎的抗炎药、治疗结肠药和直肠癌的抗肿瘤药、心脑血管药物-莱诺普利等；

The effects of heat treatment on the mechanical properties, wear-resisting property and corrosion resistance of high-entropy alloy are discussed from the aspects of the precipitation, the phase structure, the microstructure and so on, and the problems needing attention in the heat treatment process of high entropy alloys are put forward in ...
