Tailored materials are of particular interest in modern engineering applications due to their potentially high strength and residual ductility. During hot forming processes, such as press hardening, microstructure transformations low carbon steels considered achieve the production tailored components. The relevant mechanisms during thermo-mechanical processing visco-plastic deformation phase tr...

Abstract The pure titanium, as a biomaterial destined for production of load-demanding prostheses, requires thermo-mechanical processing to increase its strength. most common way achieve this is the method grain fragmentation. Thermo-mechanical deformation titanium complex process, which makes it very difficult describe by means constitutive equations. Such relations are useful they can be impl...

In this paper, the effect of various parameters on out-of-phase thermo-mechanical fatigue (OP-TMF) lifetime of A356.0 cast aluminum alloy is investigated. The studied parameters include maximum temperature, dwell time, and the thermo-mechanical loading factor. OP-TMF tests are conducted considering realistic running conditions of diesel engine cylinder heads. The maximum temperature varies betw...

Manufacturers of rolled materials are always striving to reduce the costs associated with production—be they time, material, or waste. This is especially true with the manufacture of nextgeneration particle-reinforced materials, such as those used in high-value automotive components. Process variables such as temperahire, roller speed, and plate dimensions, among others, all affect strength, du...

A comprehensive computational framework based on the finite element method for the simulation of coupled hygro-thermo-mechanical problems in photovoltaic laminates is herein proposed. While the thermo-mechanical problem takes place in the three-dimensional space of the laminate, moisture diffusion occurs in a two-dimensional domain represented by the polymeric layers and by the vertical channel...

electro-thermo-elastic stress analysis of piezoelectric polymeric thick-walled cylinder reinforced by boronnitride nanotubes (bnnts) subjected to electro-thermo-mechanical fields is presented in this article. the electro-thermo-elastic properties of piezoelectric fiber reinforced composite (pefrc) was studied by a modified xy micromechanical model capable of exhibiting full coupling relation be...

The implementation of 3-Dimensional X-Ray Diffraction (3DXRD) Microscopy at the Advanced Photon Source is described. The technique enables the non-destructive structural characterization of polycrystalline bulk materials and is therefore suitable for in situ studies during thermo-mechanical processing. High energy synchrotron radiation and area detectors are employed. First, a forward modeling ...

This paper presents the results of an experimental investigation a 12% Cr steel where significant increase in Charpy impact toughness and slight decrease ductile-brittle transition temperature (DBTT) from 70 °C to 65 were obtained through thermo-mechanical processing, including interim hot forging at 1050 with long-term annealing 1000 °C, as compared conventional heat treatment. At lower temper...
