“…Due to its comfort of use and inexpensive cost, thermal-derivative analysis (TDA) is much more suitable for industrial applications related to other thermal techniques and TDA method has been successfully used to analyse the features of aluminium, magnesium and zinc alloys in recent years [10][11][12]. In this method, the temperature changes in the sample are recorded from wholly liquid to completely solidified phases creating a curve plot of temperature as a function of time.…”

“…A cooling curve reflects the release of latent heat of solidification. This release of latent heat in multicomponent alloys changes the slope of the cooling curve which is then used to detect the characteristics of transitions and phase reactions during solidification [11][12][13]. The solidification characteristics, e.g., dendrite nucleation and dendrite coherency, can be derived from thermal analysis of the alloy solidification.…”

“…Once the dendrites become coherent, liquid metal flow is restricted to interdendritic regions. There exist four main DCP temperature testing approaches: the rheological technique (however, this method may influence DCP measurement), thermal analysis of the minimum temperature differences between two cooling curves, thermal analysis of the second derivative of cooling curve and the thermal diffusivity measurements techniques [12,14].…”

Since the forming of the microstructure depends on the specific of the casting method, which directly affects further mechanical and physical properties of the material, it is important to understand how to control the microstructure of the cast to understand changes that taking place during the crystallisation process. For estimating the metallurgical quality of the liquid metal before casting, the thermal-derivative analysis (TDA) is utilised. The TDA has been used for a long time, in both ferrous and non-ferrous industries casting. The Universal Metallurgical Simulator and Analyser (UMSA) platform is a rapid, sensitive and economical method of determining a full range of solidification features. The work focuses on the thermal analysis and heat treatment of aluminium alloys. The liquidus and solidus temperatures and dendrite coherency point (DCP) are then characterised. The research shows that the UMSA platform allows precise determination and calculation of thermal parameters. The influence of the heat treatment on structure and properties of aluminium castings has been determined as well. Heat treatment was carried out to increase the mechanical properties of aluminium alloys.Based on the findings above, the influence of microstructure on properties of the alloys is discussed.

“…Long-term impact of elevated temperature during the operation of pressure equipment and systems brings about changes in the microstructure of the material resulting in reduction of mechanical properties [5][6][7][8][9]. These changes determine the life time of components, which are now designed for 2*10 5 h of operation.…”

FORECASTING THE PARTICLE DIAMETER SIZE DISTRIBUTION IN P92 (X10CrWMoVNb9-2) STEEL AFTER LONG-TERM AGEING AT 600 AND 650 °CThe investigations on microstructure of P92 steel in the as-received condition and after 10 5 h ageing at 600 and 650 °C were carried out. For the recorded images of microstructure, the quantitative analysis of precipitates was performed.On that basis, a statistical analysis of collected data was made with the aim of estimating parameters of selected theoretical statistical distribution. Then, the forecast for average precipitate diameter and standard deviation of such a distribution for the time of 1,5*10 5 h at 600 and 650 °C was calculated. The obtained results of investigations confirm the possibility of using, in evaluation of degradation degree for materials in use, the forecasting methods derived from mathematical statistics, in particular the theory of stochastic processes and methods of forecasting by analogy.

The paper presents the results of the basic mechanical properties determined in the static tensile test, impact un-notched Charpy test and hardness of austenitic stainless steel type 316L produced by two techniques: classical pressing and sintering in a vacuum with rapid cooling and selective laser melting (SLM). In this work fracture surface of Charpy test, samples were studied.The results indicate that application of selective laser melting (SLM) makes it possible to double increase the strength properties of components manufactured from austenitic stainless steel type 316L compared to sintering in a vacuum. Resulted in mechanical properties strongly depend on porosity characteristic and the presence of superficial oxides in the case of sintered steel and the character of observed microstructural defects deriving from non-fully melted powder particles and the formation of voids between subsequently melted pool tracks during the SLM.
