The microstructure and texture evolution of Ti-5Al-5Mo-5V-1Cr-Fe alloy during hot compression were investigated by the electron backscatter diffraction technique. The results reveal that two main texture components containing <100> and <111> fiber textures form after the hot compression. The fraction of each component is mainly controlled by deformation and strain rate. Dynamic strain-induced b...

effect of small al additions, from 0.14% to 0.31% ai, on the hot deformation behavior of low carbon steels containing 1%cu-1.2%mn was investigated in the temperature range of 750-800•c over the strain rate range of 1o.3.1o.1s•1 by a hot compression testing machine. the flow curves obtained, exhibited typical characteristics of dynamic recovery type of softening mechanism, and the critical strai...

Air conditioning contributes significantly to building energy consumption in hot climate regions. In addition to greater cooling requirements in hot climates, cooling equipment efficiency decreases with increasing outdoor temperature. Therefore, it is advantageous to develop improved technologies that can achieve higher efficiency at high ambient conditions. In this paper, two novel compression...

The deformation behavior and microstructure of 25CrMo4 axle steel was systematically investigated by thermal compression deformation. hot-compression test a sample carried out on Gleeble-3800 mechanical simulation tester. flow the alloy studied at temperature (900–1200 °C), strain rates (0.01; 0.1; 1.0) s–1 maximum 60 %. curves under different conditions were obtained, effects rate appearance a...

Abstract This paper presents experimental results and finite element analysis of hot upsetting titanium alloys Ti64 Ti407 using a dilatometer in loading mode. All samples showed barrelling, as consequence an inhomogeneous temperature distribution friction. The FE is full thermomechanical model the test calibrated multiple thermocouples. At each nominal strain rate, true flow stress–strain respo...

LLE Review, Volume 126 66 Introduction High-energy electrons are detrimental to laser fusion because they can preheat the fuel, preventing the high compression necessary for central hot-spot ignition and high gain.1 The direct-drive approach is particularly vulnerable as a result of the long scale length of plasma that exists at the quarter-critical density of the target, although it can also o...
