A highly processable metallic glass: Zr41.2Ti13.8Cu12.5Ni10.0Be22.5

A Peker, WL Johnson - Applied Physics Letters, 1993 - pubs.aip.org
We report on the properties of one example of a new family of metallic alloys which exhibit
excellent glass forming ability. The critical cooling rate to retain the glassy phase is of the …

Gold based bulk metallic glass

…, B Lohwongwatana, WL Johnson, A Peker - Applied Physics …, 2005 - pubs.aip.org
Gold-based bulk metallic glass alloys based on Au–Cu–Si are introduced. The alloys exhibit
a gold content comparable to 18-karat gold. They show very low liquidus temperature, large …

Decomposition and primary crystallization in undercooled Zr41.2Ti13.8Cu12.5Ni10.0Be22.5 melts

R Busch, S Schneider, A Peker, WL Johnson - Applied physics letters, 1995 - pubs.aip.org
Zr 41.2 Ti 13.8 Cu 12.5 Ni 10.0 Be 22.5 bulk metallic glasses were prepared by cooling the
melt with a rate of about 10 K/s and investigated with respect to their chemical and structural …

Effects of electromagnetic radiation from a cellular phone on human sperm motility: an in vitro study

…, G Komesli, HC Irkilata, MK Irmak, AF Peker - Archives of medical …, 2006 - Elsevier
BACKGROUND: There has been growing public concern on the effects of electromagnetic
radiation (EMR) emitted by cellular phones on human health. Many studies have recently …

Cyber victim and bullying scale: A study of validity and reliability

B Çetin, E Yaman, A Peker - Computers & Education, 2011 - Elsevier
The purpose of this study is to develop a reliable and valid scale, which determines cyber
victimization and bullying behaviors of high school students. Research group consisted of 404 …

Blow molding of bulk metallic glass

J Schroers, Q Pham, A Peker, N Paton, RV Curtis - Scripta Materialia, 2007 - Elsevier
Blow molding is introduced as a net-shape process for bulk metallic glass (BMG). The
forming takes place in the supercooled liquid region, where the viscosity of the BMG permits …

A Peker, S Cengiz - International Journal of Psychiatry in Clinical …, 2022 - Taylor & Francis
Objective The aim of this study is to examine the mediating role of coping with stress and
psychological resilience in the relationship between happiness and perceived stress of COVID-…

Fatigue behavior of Zr–Ti–Ni–Cu–Be bulk-metallic glasses

GY Wang, PK Liaw, A Peker, B Yang, ML Benson… - Intermetallics, 2005 - Elsevier
The high-cycle fatigue (HCF) behavior of the Zr 41.2 Ti 13.8 Cu 12.5 Ni 10 Be 22.5 (in at.%)
bulk-metallic glass (BMG) was studied. Two batches of samples that are from different lots (…

Flow diversion in middle cerebral artery aneurysms: is it really an all-purpose treatment?

…, E Akgul, E Daglioglu, ED Topcuoglu, A Peker… - World neurosurgery, 2016 - Elsevier
Background and Objective The outcome of flow diversion for middle cerebral artery (MCA)
aneurysms, one of the most common sites for intracranial aneurysms, has not been defined …

Precious bulk metallic glasses for jewelry applications

…, B Lohwongwatana, WL Johnson, A Peker - Materials Science and …, 2007 - Elsevier
Families of bulk metallic glass (BMG) forming alloys based on precious metal platinum and
