Investigation of the mechanical properties of friction-welded joints between AISI 304L and AISI 4340 steel as a function rotational speed
TL;DR: In this article, a standard AISI 304L austenitic stainless steel and a AisI 4340 steel couple were welded by friction welding process using five different rotational speeds.
Journal ArticleDOI
Effect of rotational speed on the interface properties of friction-welded AISI 304L to 4340 steel
TL;DR: In this paper, the authors investigated the interface properties in terms of rotational speed in friction-welded AISI 304L to alloy steel and found that the thickness of full plastic deformed zone (FPDZ) formed at interface reduce as a result of more mass discarded from the welding interface with increase of the rotational speeds.
Journal ArticleDOI
Tungsten-inert gas surface alloying of a low carbon steel
M. Eroğlu,Niyazi Özdemir +1 more
TL;DR: In this article, the effects of thickness of the pre-placed powder layer on the microstructure, hardness and wear resistance of the alloyed surfaces were investigated, and conventional characterization techniques, such as optical microscopy, scanning electron microscopy (SEM), energy dispersive spectrograph (EDS) and X-ray diffraction were employed for studying the micro-structure of the Alloyed surface.
Journal ArticleDOI
Interfacial properties of diffusion bonded Ti-6Al-4V to AISI 304 stainless steel by inserting a Cu interlayer
Niyazi Özdemir,B. Bilgin +1 more
TL;DR: In this article, the joining characteristics of Ti-6Al-4V with AISI 304 stainless steel by inserting a Cu interlayer was investigated in a vacuum-free diffusion bonding process.
Journal ArticleDOI
Fatigue behaviour of AISI 304 steel to AISI 4340 steel welded by friction welding
TL;DR: In this article, the weldability of AISI 304 austenitic stainless steel to AisI 4340 steel joined by friction welding in different rotational speeds and fatigue behaviour of friction-welded samples were investigated.
