The AL6XN Super Austenitic Stainless Steel alloy is a commonly used steel in corrosive environments and tough applications. This paper aims to investigate the execution of a machining process on the AL6XN alloy. A wet machining process has been executed to machine the alloy under a combination...

In this study, the tool wear and surface integrity during machining of wrought and Selective Laser Melted (SLM) titanium alloy (after heat treatment) are studied. Face turning trails were carried out on both the materials at different cutting speeds of 60,120 and 180 m/min. Cutting tools and...

Cracks-free wear resistance coatings are fabricated by laser surface nitriding pure titanium and Ti-6Al-4V in an open system. The titanium nitrides which are formed in situ in the top layers of the samples are undeveloped dendritic, and thus reduce the possibility of the crack formation in the...

Composite coatings are fabricated by laser cladding of titanium alloy Ti-6Al-4V with graphite and silicon mixed powders. X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) indicate that the coatings mainly consist of pre-eutectic TiC and eutectic Ti5Si3 compounds. Test results show...

Composite coatings are produced by laser surface alloying of Ti-6Al-4V with B+Ti and B+Ni+Ti mixed powders. Test results show that the coatings have high hardness, excellent wear and oxidation resistance compared with the as-received sample. In addition, the samples alloyed with B+Ni+Ti have...

The effect of laser processing parameters on the microstructure and quality of the coatings fabricated on titanium alloy has been investigated. Results show that the increase of the output power and the decrease of the scanning speed result in the thickness increase and the microstructure...

The focus of this dissertation is on improving decision-maker trade-offs and the development of a new constrained methodology for multiple response surface optimization. There are three key components of the research: development of the necessary conditions and assumptions associated with...

The future use of electric vehicles in the southern regions of the world could face several problematics related to high temperature, mostly when charging at high power. This paper proposes a new external cooling solution for cooling EV batteries pack at higher temperature conditions especially...

We conducted an optimization using the second-order response surface method to determine the transverse rib geometry required to achieve the highest cooling performance in a circular channel. The best rib geometry was based on three design variables; rib height, rib width, and rib pitch. The...

Reliability-based structural optimization methods use mostly the following basic design criteria: I) Minimum weight (volume or costs) and II) high strength of the structure. Since several parameters of the structure, e.g. material parameters, loads, manufacturing errors, are not given, fixed...
