The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...

in this research, tribological behavior of ti-ni-p intermetallic coatings on titanium substrates have been investigated under dry reciprocating conditions. hardness profile testing results exhibit that high surface hardness has been attained and static indentation result shows that the intermetallic coating has better adhesion strength than the conventional ceramic coatings. in this respect, th...

This paper presents a brief review on titanium alloys, giving especial attention to Ti6Al-4V. The mechanical and the thermal properties were highlighted, while with regard to application the emphasis was placed to the aerospace, automotive and biomedical fields. The tensile strength of the alloys under concern varies from about 200 to 1400 MPa, but for Ti-6Al-4V the range is from about 900 to 1...

The effect of heat treatment and alloying elements of copper and tin on the microstructure and mechanical properties of austempered ductile cast iron alloys is investigated. The austenitizing temperature of 890°C, the isothermal transformation (austempering) temperatures of 285, 335 and 375°C, and austempering times of 15, 30, 75 and 150 minutes are studied. The alloying elements of copper and ...

Background: Orthodontics is a part of dentistry that includes preventive methods and correction of dental irregularities that need to be repositioned by functional and mechanical tools to provide an ideal occlusion and a beautiful face for patients. There are currently four metal arch wires used in orthodontic treatment: stainless steel alloy, cobalt-chromium alloy, nickel-titanium alloy, and b...

Shape memory alloys provide new insights for the design of biomaterials in bioengineering for the design of artificial organs and advanced surgical instruments, since they have specific characteristics and unusual properties. This article will examine (a) the four properties of shape memory alloys, (b) medical applications with high potential for improving the present and future quality of life...

The microstructure, mechanical properties, and corrosion behavior of binary Ti-xPt alloys containing 5, 10, 15 and 20 wt% Pt were investigated in order to develop new Ti-based dental materials possessing superior properties than those of commercially pure titanium (cp-Ti). All of the Ti-xPt (x = 5, 10, 15, 20) alloys showed hexagonal α-Ti structure with cubic Ti₃Pt intermetallic phase. The mech...

joining of titanium alloys to other materials especially steels has attracted much attention in recent years due to the exceptional properties of titanium such as excellent corrosion resistance and mechanical properties and its increasing application in various industries. according to the fe-ti binary phase diagram, these two elements do not have complete solubility. this leads to difficulties...

Titanium alloys exhibit high specific strength and stiffness that fit structural applications demanding lightweight. The microstructure of the alpha-beta titanium alloys can be changed by thermomechanical processes such as heat treatments and pre-forging to achieve a certain ductility. Ceramic reinforcements can improve specific strength and stiffness, and also the wear resistance. In Situ part...
