Orthogonal cutting of titanium alloys
… energy required for the orthogonal cutting of titanium alloys with the chip geometry and the mechanical properties of the material, is discussed. The solution is obtained from the extension of the apparent strain analysis of orthogonal cutting of ductile materials to the case of less ductile …

Strengthening of metastable beta titanium alloys
… behavior and properties. Metastable $\beta$ titanium alloys are a subset of titanium alloys with huge potential for the aerospace sector. However, they exhibit atomic transformations which, even after 60 years of research, are still disputed. For example, these alloys are strengthened using …

Modeling Fatigue Behavior of 3D Printed Titanium Alloys
… behavior of different microstructures of Ti-64 titanium alloy by using the PRISMS-Fatigue open-source framework. To achieve this goal Ti-64 microstructure models were created using programming scripts, then the structures were exported to a finite element visualization software package, with all …

Comparative Analysis of the Machinability of Various Titanium Alloys
Titanium alloys have a good strength to weight ratio, amazing corrosion resistance. These alloys are mostly used in the aerospace, biomedical and automotive industries. However, titanium alloys are difficult to machine since they are chemically reactive and have low thermal conductivity. Drilling …

Microstructure and mechanical behavior of metastable beta type titanium alloys
… biomaterials such as stainless steel, Co-Cr alloys, commercially pure titanium and Ti-6Al- 4V either possess poor mechanical compatibility and/or produce toxic effects in the human body after several years of usage. Consequently, there is an enormous demand for long-lasting biomaterials which …

Processing of aluminium and titanium alloys by severe plastic deformation
… microhardness<br/>measurements in the aluminium alloys was investigated after processing by ECAP and HPT. In the ECAP experiments, billets of Al-1050 alloy were processed by ECAP at room temperature using route BC for up to six passes. The results of the microhardness measurements show that the …

Effects of powder conditioning on the quality, microstructure and mechanical properties of sintered titanium alloys
… and LaB6 additions were added to Ti and Ti6Al4V alloys directly. The Ti(Ti6Al4V)-Y alloy was made by mechanical milling (MM). But direct Er additions caused a segregated microstructure and processing involving the MM of Ti(Ti6Al4V)-Y leaded to oxygen pick-up. These methods are therefore not …
