    A Simple Way for Estimating Mechanical Properties From Stress-Strain Diagram Using Matlab and Mathematica
    (Institute of Electrical and Electronics Engineers Inc., 2019) Yılmaz, Emre; Yilmaz, E.; Yavuz, S.; Yavuz, Samet; 237938; Malzeme Bilimi ve Mühendisliği; Makine Mühendisliği
    In this paper, mechanical properties of materials, e.g. ultimate tensile strength, yield stress, elastic modulus, ductility, resilience, toughness, etc., are calculated using MATLAB and Mathematica programming language and stress-strain data of any alloy. © 2019 IEEE.

    Boride Layer Growth Kinetics of Aisi H13 Steel Borided With Nano-Sized Powders
    (Polska Akad Nauk, Polish Acad Sciences, inst Metall & Mater Sci Pas, 2018) Karakaş, Mustafa Serdar; Karakas, M. S.; Gunen, A.; Yılmaz, Emre; Kanca, E.; Yilmaz, E.; Malzeme Bilimi ve Mühendisliği
    Growth kinetics of boride layers in AISI H13 steel was investigated using the pack bonding method at temperatures of 1073, 1173 and 1273 K (800 degrees C, 900 degrees C and 1000 degrees C) for periods of 2, 4 and 6 h with nano-sized boron (NB) and micron-sized Ekabor II powders as bonding agents. The total thickness of the boride layer (including both FeB and Fe2B) after boriding at 1273 K (1000 degrees C) for 6 h was 103.8 gm and 96.5 mu m for the NB and Ekabor II specimens, respectively. X-ray diffraction analysis of the boride layers on the surfaces borided with NB and Ekabor II revealed the presence of FeB and Fe2B phases with sawtooth morphology. The FeB/Fe2B volume ratio was higher in the specimens borided with NB. The thickness of the boride layer (FeB + Fe2B) increased with the increasing boriding temperature and time. The FeB layer in the NB specimen displayed a (002) preferred orientation.
