“…Many researchers investigate the wear behavior of different heat-treated parts in terms of various parameters to meet the industry's wear performance requirements [17][18][19][20]. According to the studies reviewed, heat treatment and manufacturing processes, in general, aim to optimize the surface hardness and wear characteristics of the components.…”

Original scientific paperCompacted graphite iron (CGI) is a critical material in today's automotive and manufacturing industries. Heat treatment processes can improve CGI wear properties, related primarily to microstructural changes. In this study, single and double tempering heat treatments were carried out to improve the wear properties of CGI. Oil quenching was performed after 90 minutes of austenitization at 900°C, followed by 60 minutes of single and double tempering at three different temperatures (315, 350, and 375°C). The wear performance of the samples was compared using a pin-on disc test and hardness measurements. The volume loss and friction coefficient were evaluated, and wear maps were constructed to determine the samples' wear behavior. SEM and EDS analyses were carried out to worn surfaces to interpret the wear mechanisms. According to the study's findings, double tempering heat treatment may optimize wear performance better than traditional single tempering, and structures with high toughness-wear resistance combinations can be obtained.

In order to obtain better mechanical properties in a bronze alloy, it is important to produce new materials by adding reinforcements and to offer these materials to the industry. In this study, bronze matrix (Cu10Sn) materials were reinforced with boron carbide (B4C) and silicon carbide (SiC) ceramic materials by using the mechanical alloying method. New composite materials were produced by powder metallurgy method by adding ceramic reinforcement (B4C and SiC) at 1, 2, 4 and 8 weight ratios to Cu10Sn alloy, which is the main matrix material. The obtained composite materials examined in terms of structural, microhardness and wear resistance. Coefficient friction, specific wear rate and volume loss rates under 5N, 10N, and 15N loads were examined for the samples produced. When the applied microhardness and wear behaviors were examined, it was generally seen that the hardness and wear behaviors were improved with the added reinforcement ratios. In line with the examinations made, based on the hardness and wear processes applied to the materials consisting of the bronze matrix of the reinforcement material, it was observed that the most appropriate results were obtained from composite materials (Alloy 4 and Alloy 8), which contain 4% B4C and SiC reinforcement.

In this study, Ti6Al4V (Grade 5) alloys were first dissoluted at 850?C for 120 min. and then were aged at 250?C, 350?C, 450?C, 550?C, 650?C and 750?C respectively. After each aging duration (by looking at hardness ratios aged between 9 to 54 hours), the hardness of the samples was measured. Depending on the aging temperature and time increase, hardness increased upon the formation of ?' phases. After the formation of ?' phases, the hardness started to decrease. The highest hardness value was measured in the sample aged at 450?C for 24 hours. The wear behavior of the untreated and the aged samples was investigated through a detailed pin-on-disc test. The effect of the aging temperature on the volume loss, the specific wear rate, and the coefficient of friction were examined. Metallographic analyses were performed before and after the wear tests. Both abrasive and adhesive wear formations were observed on the FESEM-EDS images of the worn surfaces. When the results were evaluated, it was observed that the highest hardness and good wear behavior were obtained for the samples aged at 450?C for 24 hours.
