...Venkateswaran Perumal; Sivakumar Palanivelu; Siba Prasad Mookherjee; Ajit Kumar Jindal The present paper investigates the microstructure and mechanical properties’ aspects of AISI 4140 steel front axle beams developed by roll and hot-die forging processes. Microstructure of the processed beams...

...Weng-Sing Hwang; Tian-I Wu; Wen-Chung Sung The effects of postrolling heat treatment on the mechanical property and microstructure of 1050 aluminum alloy and 304 stainless steel (SS) clad metals were investigated. Clad metals were made by cold rolling after surface treatments of both sheets...

... with a three roll milling technique. XD-grade carbon nanotubes (XD-CNTs) were infused into Epon 862 epoxy and the mixture was then mechanically mixed with a mechanical stirrer before placing into a sonicator. This mixture was submerged continuously in a cooling bath to prevent premature polymerization. Once...

...) is used to produce wires of Nitinol and compare its efficacy with wires produced conventionally by hot rolling. With two four to one area reductions, a wire of 3 mm diameter was formed by IHNCIE. The extruded wires showed good superelastic tensile properties. This 3 mm diameter extruded wire exhibited...

... strain at various locations in a specimen for comparison with computations based on finite element models using various constitutive relations or phase field simulations of grain growth or deformation. Experimental measurements of grain strains at the center of a ferritic steel sheet rolled in nominally...

... to the rolling direction or to the punch surface did not influence the formability, as the softened zone dominated the formability behavior. It was observed that in both uniaxial and biaxial strain tests, the fracture occurred in the softened zone of the welded samples consistently slightly farther out from...

...Yuri Estrin; KiHo Rhee; Rimma Lapovok; Peter F. Thomson An established dislocation density related, one-internal variable model was used, with some modifications, as a basis for modeling the mechanical response of aluminum alloy AA6111. In addition to conventional rolling, equal channel angular...

... steel forming processes softening texture work hardening plastic deformation X-ray diffraction rolling simulation dislocation structure Sheet metal forming of low carbon steels is of considerable applied importance. Accurate prediction of Forming Limit Diagrams (FLDs) involves 1...

... a maximum in modulus and a minimum in Poisson’s ratio at 45 deg to rolling direction. To describe the combination of recoverable inelastic and elastic deformation as a function of plastic prestrain, a set of equations has been developed based upon a previously developed constitutive model. Calculated...

...Jingyu Shi; D. L. S. McElwain; S. A. Domanti In view of the well-known disparity between predictions from temper rolling models and measured values from rolling mills, there is a need to obtain a better understanding of the effect of roll asperities on the yielding characteristics of the rolled...

...Seung-Hyun Hong; Dong Nyung Lee A study has been made of the deformation and recrystallization textures of 99.99% pure copper sheets which were cross rolled by 82 and 96% reduction in thickness and recrystallized in a salt bath at 450°C for 1h. The deformation texture was approximated by the {011...

...M. P. Miller; N. R. Barton Rolled aluminum alloys are known to be anisotropic due to their processing histories. This paper focuses on measuring and modeling monotonic and cyclic strength anisotropies as well as the associated anisotropy of the elastic/elastic-plastic transition of a commercially...
