Sac Metal Malzemelerin Ilık Derin Çekme Yöntemiyle Şekillendirme Prosesinde Malzeme Karekterizasyonu

Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2015
Ilık derin çekme yöntemiyle şekillendirme prosesinde malzeme karakterizasyonu önemli bir aşamadır. Bu çalışmada; 1,2 mm ve 1,5 mm sac kalınlıklarında HC300LA (Erdemir 7128) ve HC420LA (Erdemir 7140) sac malzemelerinin ılık derin çekme ile şekillendirme ...

Finite element simulation of ironing process under warm conditions

Journal of Materials Research and Technology, 2014
Metal forming is one of the most important steps in manufacturing of a large variety of products. Ironing in deep drawing is done by adjusting the clearance between the punch and the die and allow the material flow over the punch.

Finite element analysis of non-isothermal warm deep drawing of dual phase steel

MATEC Web of Conferences, 2016
Improving the formability of the material is an important issue in the deep drawing process. Heating the material above its recrystallization temperature drastically increases formability but in the case of dual phase (DP) steels it results in the loss ...

Toward a Circular Economy in Deep Drawing: Remanufacturing End-of-Life Automotive Parts [PDF]

MATEC Web of Conferences
Recycling aluminium typically involves energy-intensive melting processes. This study presents a more sustainable approach by directly remanufacturing deep-drawn parts from end-of-life aluminium automotive components.

Circular and square cups drawing and ironing of Ti alloy sheets by incremental press forming method [PDF]

MATEC Web of Conferences
The low ductility of Ti–6Al–4V alloy at forming temperatures below 780°C is still a problem. Ti–6Al–IV alloy is usually hot press formed at 780 to 900°C.

Comparison of the Mechanical Properties and Forming Behavior of Two Texture-Weakened Mg-Sheet Alloys Produced by Twin Roll Casting

Frontiers in Materials, 2019
The influence of rolling and annealing on the resulting mechanical properties and forming behavior of Mg-Zn-RE and Mg-Zn-Ca alloys produced via twin roll casting is investigated. After hot rolling followed by an annealing treatment, both alloys develop a

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
