High energy input additive manufacturing (AM) such as wire-based directed deposition technologies are capable of high rates but can result in coarse microstructures along with potentially large defects gas porosity. The presence and the adverse effect on mechanical properties is further exacerbated when low-quality or contaminated feedstock materials used. This work demonstrates a pathway for producing high-quality additively manufactured products that ordinarily would be considered...
Non-destructive x-ray methods such as micro-computed tomography (micro-CT) are useful for investigating porosity defects in additively manufactured products. Understanding the knowledge accessible to micro-CT technologies relies on quantifying spatial and morphological characteristics of instances. So far, machine learning-based semantic segmentation techniques threshold-based image analysis have been employed this purpose. However, reliability these is compromised by their limitations...
Super β-transus hot isostatic pressing (HIPing) has been shown to be able transfer columnar equiaxed grains in additively manufactured Ti–6Al–4V. Although pores the parts have found play a role such grain transformation, it remains unclear whether super HIPing can also generate isotropic microstructure and mechanical properties relatively high-density In present study, (1030 °C, 175 MPa) was applied high density Ti–6Al–4V by laser powder bed fusion (L-PBF). As comparison, specimens were...
β‐flecks are a type of segregation defect commonly encountered during the solidification titanium alloys enriched with β‐stabilizing elements. These defects associated detrimental impact on mechanical properties, which potentially limit service life parts containing them. Despite their significance, standardized method for identifying these is lacking. In this study, systematic approach provided to detecting and characterizing in representative metastable β‐Ti alloy β‐C (ASTM Grade...
The surfaces of artificial joints are susceptible to premature wear which reduces their service life leading the increased risk revision arthroplasty. Tribological coatings having low coefficients friction (CoF) and also biocompatible therefore required minimise such risks. Metal matrix composite (MMC) exhibiting a modified toughness structure, thus reducing potential crack were successfully fabricated by cold spray (CS) technology. comprised an ultra-low polytetrafluoroethylene (PTFE) +...
β-type Ti-alloy is a promising biomedical implant material as it has low Young's modulus and also known to have inferior surface hardness. Various treatments can be applied enhance the Physical vapor deposition chemical are two examples of this but these techniques limitations such poor interfacial adhesion high distortion. Laser treatment relatively new modification method hardness its application still not accepted by industry. The major problem process involves melting which results in...
Heavy metal pollution is one of the most serious environmental problems in world. Many efforts have been made to develop biosensors for monitoring heavy metals environment. Development nanoparticle-based effective way solve this problem. This review presents latest technology environment detect ions, which are magnetic chitosan biosensor, colorimetric and electrochemical biosensor. Magnetic biosensor acts as a nanoabsorbent, can easily extract poisonous ions such lead copper ions. There...
