Titanium-based alloys are constantly improved to obtain properties suitable for their use. Improving titanium alloys is very important for performing alloys without side effects. In this paper effects of structure, microhardness, and indentation test of eight titanium alloys were investigated after aging. The heat treatment consisted of a high-temperature quenching accomplished in three steps (650 °C for 25 min, 850 °C for 20 min, and 950 °C for 20 min). The cooling process was accomplished using N₂ gas, introduced in the chamber at a 9-bar pressure for 37 min. Then, followed by heating to a constant temperature tempering (550 °C) at 1.5 bar pressure and kept for 2 h and 10 min at 2 bar pressure. Optical microscopy images were obtained of Ti-Mo-Zr-Ta alloys with grain-specific aspects of titanium alloys; acicular and coarse structures are specific to β alloys. Microhardness results showed significantly influenced by the heat treatment, increased by approximately 5% for Ti15Mo7Zr15Ta1Si and Ti20Mo7Zr15Ta0.5Si, while for Ti15Mo7Zr15Ta0.5Si and Ti20Mo7Zr15Ta an approximately 9% decrease has been noted. The modulus of elasticity results obtained by the indentation method for the experimental alloys were between 36.25–66.24 GPa. The heat treatments applied to the alloys had a pronounced effect, improving both the structure of the alloys and the results of the indentation test.

European legislation stipulates the obligation to carry out a risk assessment for each job, as well as the application of measures to prevent these occupational risks. Therefore, taking into account the importance of risk determination at the workplace for the prevention of work accidents and occupational diseases, this paper proposes the digitization of a risk assessment method. The application of the occupational injury and illness risk assessment method begins with a document that contains a description of the company (name, location, domain of activity, organization chart, etc.), a description of the work system detailing its components and a brief description of the assessment method. Next follows a Microsoft Excel document that performs the actual application of the method. Finally, another document presents the list of measures that lead to the implementation of the prevention and protection plan. This paper presents the code design of the Microsoft Excel document, an essential part in the application of the method of assessing the risks of occupational injury and illness. The document is structured on a variable number of worksheets, which present the different types of occupational injury and illness based on risks on the components of a work system. The digitalization of the risk assessment method reduces the time allocated to the evaluation without affecting its quality.
