Recast layer removal using ultrafast laser in titanium alloy
The International Journal of Advanced Manufacturing Technology, 2013Recast layer, which has undesirable effects on the fatigue resistance and service life of components and microstructures, has been observed and analyzed from the points of surface morphology and internal microstructure by three test methods including scanning electron microscopy, metallographic corrosion analysis, and transmission electron microscopy ...

Investigations Into the Removal of EDM Recast Layer With Magnetic Abrasive Machining
Volume 1: Processing, 2015Electrical Discharge Machining (EDM) is a non conventional machining process capable of accurately machining parts with high hardness and of complex shapes. The sparks produced during the EDM process cause localized melting on the work surface. The formation of recast layer is very common on EDMed surfaces.

Journal of Materials Engineering and Performance, 2017
In this study, electrical discharge machining (EDM) is used to directly drill normal effusion cooling holes in thermal-barrier-coated nickel-based superalloys (TBCs) via the assisting electrode method. The formation of the conductive layer was studied using scanning electron microscopy and energy-dispersive spectroscopy.

The experimental study on recast layer removal of metallic material by femtosecond laser
PICALO 2010: 4th Pacific International Conference on Laser Materials Processing, Micro, Nano and Ultrafast Fabrication, 2010The microcracks and impurities in the recast layer have undesirable effects on the fatigue resistance and service life of metallic parts. In order to overcome the drawbacks, a new method of recast layer removal based on the advanced femtosecond laser process technology is proposed in this paper.

Nanoscale carbide precipitation in the recast layer of a percussion laser-drilled superalloy
Scripta Materialia, 2009The microstructure of the recast layer formed during percussion laser drilling of a powder-metallurgy Ni-based superalloy has been studied using electron microscopy in conjunction with focused ion beam serial section tomography. It is shown that the dendritic microsegregation of Ti in the supersaturated gamma recast grains reported previously is ...

Correlation of surface roughness and recast layer thickness in electrical discharge machining
Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2015Electrical discharge machining (EDM) is an extensively used method in the machining of electrically conductive materials. Recast or white layer formation is undesirable, but inevitable, result of EDM and needs to be understood and accurately determined to efficiently perform post-treatment processes for removing the recast layer caused by EDM process ...

Effect of temporally modulated pulse on reducing recast layer in laser drilling
The International Journal of Advanced Manufacturing Technology, 2016Temporally modulated-pulse laser is a promising technique; it has many advantages compared with normal pulse laser. The modulated pulse studied in this work was comprised of a wide pre-heating pulse front and a sharp pulse trail. The experiments were carried out mainly to study the influence of pre-heating subpulse energy and duration, while the trail ...

Study on recast layer thickness and residual stress during WEDM of SMAs
Emerging Materials Research, 2017Shape memory alloys (SMAs) are difficult to machine by thermoelectric processes due to the affinity of titanium (Ti) for oxygen, and the specific properties of SMAs have been taken into account for the design of SMA actuators. In this investigation, wire electro-discharge machining of a specific SMA is investigated with specific reference to the ...
