A new approach to sintering and boriding of steels "Boro-sintering": Formation, microstructure and wear behaviors 

Erdoğan, Azmi; Kurşuncu, Bilal; Günen, Ali; Kalkandelen, Müge; Gök, Mustafa Sabri (Elsevier, 2020)
In this study, sintering and boriding methods are applied as a single step, and it is aimed to gain time and economic advantage. For this purpose, powder mixtures prepared in suitable compositions were subjected to sintering ...

Effect of Different Arc Welding Processes on the Metallurgical and Mechanical Properties of Ramor 500 Armor Steel 

Günen, Ali; Bayar, Selçuk; Karakaş, Mustafa Serdar (Asme, 2020)
In the present study, Ramor 500 armor steel plates were automatically welded using cold metal transfer arc welding (CMT), gas metal arc welding (GMAW), and hybrid plasma arc welding (HPAW) methods. To investigate the effects ...
