    Strain Hardening Behavior Characterization of Dual Phase Steels
    (2018) Davut, Kemal; Şimşir, Caner; Çetin, Bariş
    The requirements for higher passenger safety, improved fuel economy and weight reductionin automobile industry necessitates the usage of advanced high strength steel (AHSS)grades. Dual phase (DP) steels are the most widely used one among AHSS. DP steels becomeincreasingly popular, since they provide a combination of sufficient formability at room temperatureand tensile strength over 1000 MPa. The current standards for DP steels only specifiesyield and tensile strength. Steels from various producers have considerably different compositionand microstructure; however they still have the same grade name. Combined withthe inherited heterogeneous microstructure, those steels exhibit different strain hardeningbehavior. The aim of this study is to evaluate the strain hardening behavior of DP800 steels,obtained from different vendors and thus having different compositions and microstructures.The strain hardening behavior was characterized with tensile tests performed along rollingand transverse directions. The microstructure has been characterized with optical andscanning electron microscopes. The martensite fraction, grain size of ferrite and chemicalcomposition has been correlated to the strain hardening behavior. The results show thatthe steel with more micro-alloying addition has finer ferritic grain size, which cause higherinitial strain hardening rate. The steel with higher Mn and Cr has higher martensite fraction,which cause strain hardening rate to be higher at higher strain levels.

    Elektrik Direnç Punta Kaynağı ile Birleştirilen %15 Deforme Edilmiş Twıp Çeliğinde Kaynak Akımının Mikroyapı ve Mekanik Özellikler Üzerindeki Etkisi
    (Gazi Univ, Fac Engineering Architecture, 2020) Aydın, Hakan; Tutar, Mümin; Davut, Kemal; Bayram, Ali
    Çalışmada, %15 deforme edilmiş TWIP saclarının elektrik direnç punta kaynağıyla birleştirmelerindekaynak akımının mikroyapı ve mekanik özellikler üzerindeki etkisi incelenmiştir. Mikroyapıkarakterizasyonunda optik mikroskop, taramalı elektron mikroskobu (SEM), SEM/Enerji dağılımlı X-ışınıSpektroskopisi (SEM-EDS) ve SEM/Elektron Geri Saçılım Kırınımı (SEM-EBSD) teknikleri kullanılmıştır.Mekanik özelliklerin belirlenmesinde, mikrosertlik ölçümleri ve çekme testleri yapılmıştır. Kaynak akımıartışı ile erime bölgesindeki kaynak boşlukları azalırken, çekirdek çapı, çökme miktarı ve ısı tesiri altındakibölge (ITAB) genişliği yaklaşık lineer bir şekilde artmıştır. Kaynak bölgesinde deformasyon ikizleri ortadankalkarken, ITAB’da iri tavlama ikizleri ortaya çıkmıştır. Ayrıca, kaynak akımı artışıyla ITAB’daki taneirileşmesi ve ikiz kalınlıkları artmıştır. Ancak, kaynak işlemi kaynak bölgesinde herhangi bir fazdönüşümüne neden olmamıştır. Bu sebeple, kaynak bölgesi sertlik değerleri temel malzemenin sertlikdeğerlerinden oldukça düşük kalmıştır. Genel itibariyle, en düşük sertlikler ITAB’da gözlenmiştir. Kaynakakımı ile kaynak bölgesi sertlik değerleri arasında herhangi bir korelasyon elde edilmemiştir. Kopma yükükaynak akımı ile artmıştır: En yüksek kopma yükü 10 kA kaynak akımında elde edilmiştir. Düşük kaynakakımlarında aryüzey tipi kırılma meydana gelirken yüksek kaynak akımlarında buton çekirdek tipi kırılmalarortaya çıkmıştır. Kırılma karakteristikleri genel itibariyle gevrek-sünek karışımıdır. Daha yüksekmukavemete sahip numunelerde gevrek-sünek kırılma bölgesinde sünek kırılma, gevrek kırılma bölgesindeise trans-granular kırılma karakteristikleri artış göstermiştir.

    Microstructural Analysis of Austempered Ductile Iron Castings
    (2016) Çetin, Barış; Meco, Halim; Davut, Kemal; Arslan, Ebru; Uzun?, Mustafa Can
    Austempered ductile iron (ADI) castings have a wide range of application areas in engineering designs due to their promising mechanical properties and lower cost. ADI has very good strength and toughness values at the same time its ductility is relatively high compared to most of the other cast irons. These promising mechanical properties originate from combination of specific graphite and matrix microstructure. The size, shape and fraction of graphite as well as the matrix microstructure influences the mechanical properties. In this paper the efforts regarding to a localization project of ADI is presented. In a more detailed manner, the first locally produced ADI which cannot satisfy the mechanical properties stated in ISO 17804 is compared with the original sample which is conform with the standard. The two pieces are inspected by mechanically and microstructurally by means of which necessary actions are detected for the local production. In other words the relation between the macro mechanical properties and the microstructural conditions are tried to be clarified.
