Hot torsion test (HTT) has extensively been used to analysis and physically model flow behavior and microstructure evolution of materials and alloys during hot deformation processes. In this test, the specimen geometry has a great influence in obtaining reliable test results. In this paper, the interaction of thermal-mechanical conditions and geometry of the HTT specimen was studied. The commer...
The deformation behavior of homogenized Al-7.5Zn-1.5Mg-0.2Cu-0.2Zr alloy has been studied by a set of isothermal hot compression tests, which were carried out over the temperature ranging from 350 °C to 450 °C and the strain rate ranging from 0.001 s-1 to 10 s-1 on Gleeble-3500 thermal simulation machine. The associated microstructure was studied using electron back scattered diffraction (EBSD)...
Purpose In fire resistance tests (FRTs) of building materials, a crucial criterion to pass the test procedure is avoid leakage hot flue gases caused by gaps and cracks occurring due thermal exposure. The present study's aim calculate deformation steel door, which embedded within wall made bricks, qualitatively determine gas leakage. Design/methodology/approach A computational fluid dynamics/fin...
