Effects of electropulsing assisted ultrasonic impact treatment on welded components

Materials Science and Technology, 2015
The effect of electropulsing assisted ultrasonic impact treatment (EUIT) on the mechanical properties and microstructure evolution of S50C steel welded components has been investigated. The present paper presents the application of a relatively new post-weld treatment method to eliminate the residual stress and improve the surface mechanical ...

The improved superelasticity of NiTi alloy via electropulsing treatment for minutes

Journal of Alloys and Compounds, 2014
Abstract Mechanical testing, transmission electron microscopy, X-ray and electrical resisitivity measurement were employed to study the superelasticity and microstructure of cold-rolled NiTi shape memory alloy subjected to electropulsing treatment (EPT) for more than 2.5 min.

Microstructure and Texture Evolution of Magnesium Alloys During Electropulse Treatment

Metallurgical and Materials Transactions A, 2015
Two magnesium alloys AZ31 and ZEK100 were subjected to cold rolling followed by electropulse treatment (EPT) for different durations in order to investigate the microstructure and texture evolution during EPT. AZ31 started to recrystallize once the electropulse current was applied. ZEK100, in contrast, exhibited two-stage recrystallization before which

Rapid hardening of AISI 4340 steel induced by electropulsing treatment

Materials Science and Engineering: A, 2018
Abstract Mechanisms for the rapid hardening induced by electropulsing treatment (EPT) in an AISI 4340 steel were investigated by X-ray-diffraction analysis, transmission electron microscopy observations and Vickers microhardness tests. It is found that the combined strengthening effects induced by solid-solution atoms, dislocations, and nano-twins ...

Recrystallized microstructure in cold worked brass produced by electropulsing treatment

Materials Letters, 2004
Recrystallized microstructure and mechanical properties of a cold worked brass were studied. The results showed that smaller recrystallized grains could be obtained by using electropulsing; thus, mechanical properties of the material could be improved. The mechanism of formation of smaller recrystallized grains was discussed.

Effects of Electropulsing Treatment on Microstructure and Properties of Cemented Carbide (WC-15Co)

Metallurgical and Materials Transactions A, 2020
Electropulsing treatment (EPT) is a promising postprocessing method to optimize microstructure. In the present work, the EPT was applied to treat cemented carbide (WC-15Co). The electropulse-induced microstructural evolution in WC-15Co was investigated. Compared with the untreated sample, the transverse rupture strength and electrical resistance of the

Effect of electropulsing treatment on the crystallization kinetics of Zr55Ni5Al10Cu30 bulk metallic glass

Thermochimica Acta, 2012
Abstract Zr 55 Ni 5 Al 10 Cu 30 bulk metallic glass with a diameter of 3 mm was prepared by copper-mold suction casting combined with covering flux technology under non-vacuum conditions. The non-isothermal crystallization kinetics of Zr 55 Ni 5 Al 10 Cu 30 bulk metallic glass prepared with and without electropulsing treatment on the molten alloy ...

Crystallization of a Ti-based Bulk Metallic Glass Induced by Electropulsing Treatment

Journal of Iron and Steel Research International, 2016
The effect of electropulsing treatment (EPT) on the microstructure of a Ti-based bulk metallic glass (BMG) has been studied. The maximum current density applied during EPT can exert a crucial role on tuning the microstructure of the BMG. When the maximum current density is no more than 2720 A/mm2 the samples retains amorphous nature, whereas, beyond ...

Effects of High Density Electropulsing Treatment on Aging Kinetics of GH4199 Alloy

Rare Metal Materials and Engineering, 2011
Abstract GH4199 alloy was treated by high density electropulsing for different time, and the microstructure evolution and tensile properties were examined. The results show that the diffusion of solute atoms in GH4199 alloy can be strongly accelerated by electropulsing.
