Dataset for research paper entitled "Spontaneous room temperature reaction of titanium and its alloys with hydrogen during self-shearing reactive milling"

The dataset contains the result of the experiment showing the room temperature reaction of the titanium and its alloys with hydrogen. The reaction was performed in a planetary ball mill, under hydrogen pressure without any grinding media. The whole experiment is described in the article being submitted (reference will be given after acceptance). The list of files with the description is given in separate excel file. The dataset is composed of both the raw and processed data: X-ray phase analysis - performed with a Rigaku Ultima IV diffractometer equipped with a cobalt anode lamp and parallel beam geometry. XRD patterns obtained for titanium powder milled under hydrogen pressure with different rotational velocities. XRD patterns of the samples after spontaneous hydrogenation - the milling vial was stopped after the reaction was initiated, and the observed pressure drop in the vial was ~10 bar. XRD patterns showing the phase evolution of titanium alloys after room-temperature hydrogenation. Temperature and pressure during reactive milling - reactive milling was performed using a P6 Fritsch planetary mill with a custom-made stainless steel (AISI 316) vial. The milling vial was designed to allow it to wirelessly transmit and store pressure and temperature signals (TDWLB-DL3000132 sensor, 200 bar range, 0.25% accuracy, Transducers Direct®, USA). Hydrogen absorption curves for different rotational speeds of the pressure vial - samples were stored and loaded into the vials in air. Hydrogen absorption curves for different rotational speeds of the pressure vial - powder stored and loaded into the vial in a glovebox in high-purity argon. Hydrogen absorption curves obtained in an experiment in which the milling vial was stopped after the reaction was initiated, and the observed pressure drop in the vial was ~10 bar. · Hydrogen absorption curves for different types of titanium alloys representing α, α+β, and β types Thermogravimetric analysis (TGA) - TGA was performed with a Labsys TGA instrument (Setaram, France) under argon flow. Thermogravimetric curves obtained for the decomposition of powder after synthesis at 500 rpm. Thermogravimetric curves obtained an experiment in which the milling vial was stopped after the reaction was initiated, and the observed pressure drop in the vial was ~10 bar. Thermogravimetric curves obtained for fully hydrogenated samples of Ti Gd-2, Ti Gd5, Ti-5553. The Brunauer–Emmett–Teller (BET) specific surface area (SSA) of the selected samples was measured with a Micromeritics ASAP 2020. Analyzer BET SSA of samples before hydrogenation and after hydrogenation at 500 rpm - Ti Gd-1.本数据集包含钛及其合金与氢气在室温下发生反应的实验结果。该反应在行星式球磨机中进行，反应全程处于氢气氛围且未添加任何研磨介质。完整实验细节见于已投稿的学术文章，录用后将提供参考文献。各文件的说明清单详见单独的Excel文件。 本数据集涵盖原始数据与处理后数据两类： 一、X射线物相分析（X-ray phase analysis）：采用搭载钴阳极灯与平行束光路的Rigaku Ultima IV型X射线衍射仪完成测试。 1. 不同旋转转速下，氢气氛围中球磨钛粉末得到的X射线衍射（XRD）图谱； 2. 自发氢化后样品的X射线衍射（XRD）图谱：反应启动后停止球磨罐，此时罐内压力下降约10 bar； 3. 钛合金室温氢化过程中的物相演变X射线衍射（XRD）图谱。 二、反应球磨过程中的温度与压力数据：实验采用P6型Fritsch行星式球磨机，搭配定制的不锈钢（AISI 316）球磨罐。该球磨罐可无线传输并存储压力与温度信号（TDWLB-DL3000132型传感器，量程200 bar，精度0.25%，Transducers Direct®，美国）。 1. 不同旋转转速下的吸氢曲线：样品在空气中存放并装入球磨罐； 2. 不同旋转转速下的吸氢曲线：粉末在高纯度氩气氛围的手套箱中存放并装入球磨罐； 3. 反应启动后停止球磨罐的实验吸氢曲线：此时罐内压力下降约10 bar； 4. 代表α、α+β及β型的不同钛合金的吸氢曲线。 三、热重分析（Thermogravimetric Analysis, TGA）：采用法国Setaram公司的Labsys TGA型热重分析仪，在氩气气流下完成测试。 1. 500 rpm转速下合成后粉末分解的热重曲线； 2. 反应启动后停止球磨罐的实验热重曲线：此时罐内压力下降约10 bar； 3.
