Influence of aging process and reinforcement ratio on physical and mechanical properties of carbonized aramid reinforced Al7075 materials Demir, Mehmet Emin; Çelik, Yahya Hışman; Kalkanlı, Ali (2023-01-01) The high mechanical properties, corrosion resistance and low production costs of aluminum alloys make their use in the aerospace and automobile industries attractive. Addition of reinforcement, and heat treatment are impor...
The effect of B4C reinforcements on the microstructure, mechanical properties, and wear behavior of AA7075 alloy matrix produced by squeeze casting Demir, Mehmet Emin; ÇELİK, YAHYA HIŞMAN; KILIÇKAP, EROL; Kalkanlı, Ali (2022-11-01) Aluminum and its alloys have become the most popular materials in applications aiming to provide lightness due to their low density. However, the low mechanical properties compared to other competitors are among the disadv...
The Effect of Rolling and Aging on Mechanical and Tribological Properties in B4C Particle Reinforced Al7075 Matrix Composites Demir, Mehmet Emin; Çelik, Yahya Hışman; Kalkanlı, Ali (2022-01-01) © 2022, King Fahd University of Petroleum & Minerals.Strengthening, heat treating, or rolling these alloys with different reinforcement particles positively affects the physical, mechanical and tribological properties. In ...
Effect of isothermal transformation treatment and tempering on the microstructure and hardness of a medium c and high si steels KAFADAR, Gülten; Kalkanlı, Ali; ÖZDEMİR, ABBAS TAMER; Ögel, Bilgehan (2021-01-01) This research work aims to study the effect of 2wt%Mo on bainitic transformation kinetics and bainite morphology in 0.6wt%C-1.2wt%Si-1.0wt%Mn-0.2wt%Cr steel. Specimens are austenitized at 950°C and rapidly cooled in salt b...
Investigation of wear behavior of aged and non-aged SiC-reinforced AlSi7Mg2 metal matrix composites in dry sliding conditions ÇELİK, YAHYA HIŞMAN; Demir, Mehmet Emin; KILIÇKAP, EROL; Kalkanlı, Ali (Springer Science and Business Media LLC, 2020-01-01) Metal matrix composites (MMCs) with their splendid mechanical properties have been specifically designed for use in fields such as aerospace and aviation. The presence of hard ceramic particles in MMC increases the hardnes...
Refinement of primary carbides in AISI DC 53 cold work tool steel by thin section copper permanent mould casting and water atomization ÇARDAKLI, İSMAİL SEÇKİN; Kalkanlı, Ali (Informa UK Limited, 2019-05-01) In this study, as alternative methods to conventional production methods involving thin section copper permanent mould casting (fast solidification) and water atomization (rapid solidification) of AISI DC 53 cold work tool...
Effect of solidification rate on microstructure and primary carbides of AISI DC 53 cold work tool steel Cardakh, Ismail Seckin; Kalkanlı, Ali (Springer Science and Business Media LLC, 2019-05-01) The solidification behavior of AISI DC 53 cold work tool steel was investigated by means of a cooling curve and its first derivative. Copper and sand wedge-shaped molds were used to obtain various solidification rates. To ...
Processing and microstructural characterization of liquid phase sintered tungsten-nickel-cobalt heavy alloys DINCER, Onur; PEHLIVANOGLU, M. Kaan; CALISKAN, N. Kaan; Karakaya, İshak; Kalkanlı, Ali (2015-05-01) In this.study, the effects of composition and sintering temperature on the microstructural characteristics of liquid phase sintered 90W-Ni-Co alloys were investigated. 90W-Ni-Co alloys having Ni/Co ratios of 3/1, 4/1 and 6...
Dry sliding wear behaviour of Al-Fe-Si-V alloys at elevated temperatures Koraman, Emrah; Baydoğan, Murat; Sayilgan, Seda; Kalkanlı, Ali (2015-01-15) High temperature strength of Al-Fe-V-Si alloys due to quaternary silicide dispersoids in their microstructures has been well documented in the literature. In those works, these materials have been shown as promising candid...
