The effect of aging temperature and aging duration on the dry sliding wear behavior of Ti6Al4V alloy
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.
期刊介绍：
Science of Sintering is a unique journal in the field of science and technology of sintering.
Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published.
Science of Sintering journal is published four times a year.
Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
