In this paper an e cient sequential approach for simulating thermal stresses in brake discs for repeated braking is presented. First a frictional heat analysis is performed by using an Eulerian formulation of the disc. Then, by using the temperature history from the rst step of the sequence, a plasticity analysis with temperature dependent material data is performed in order to determine the co...

Microstructure, mechanical properties and phase transformation of a heat-resistant rare-earth (RE) Mg-16.1Gd-3.5Nd-0.38Zn-0.26Zr-0.15Y (wt.%) alloy were investigated. The as-cast is composed equiaxed α-Mg matrix, net-shaped Mg5RE Zr-rich phases. According to aging hardening curves tensile variation, the optimized condition solution treatment at 520 °C for 8 h subsequent 204 12 was selected. con...

Engineering components are usually manufactured with sequential production processes. Work hardening due to previous processes affects the machinability of workpiece in subsequent operations. In this research, surface work a by two heat treatment/milling (HT + M) and milling/heat treatment (M HT) superalloy GH4169 was investigated. First, microstructure characteristics, including plastic deform...

The AZ80 magnesium (Mg) alloy cabin component with high strength and excellent ductility was developed by W-shaped channel extrusion (WCE) at 350 °C subsequent T6 heat treatment. effect of WCE process on the microstructure mechanical properties experimentally investigated, age-hardening behavior evolution during treatment revealed. Due to introduction multi-stage asymmetric severe shear deforma...

X-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of Fe-10Ni-7Mn (wt. %) maraging steel. Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...

Abstract To combine the advantages of two materials, hybrid bulk metal workpieces are attractive for subsequent processes such as forming. However, materials rely on initial bond strength effective transfer applied loads. Thus, a non-destructive evaluation bonding along production process chain is high interest. evaluate to what extent testing can be employed monitor quality between joining par...

Ordering process and age-hardening mechanism of CuPd-AuCu pseudo-binary alloys were examined In alloys with electron-atom ratios (e/a)<0.87, short range ordering was observed in the early stage of aging, thereafter, long range ordering occurred from grain boundaries by heterogeneous ordering mecha nism. Age-hardening of these alloys was attained by the increase in volume fractions of CuPd and/o...
