Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...

The hot deformation behavior and processing characteristics of AZ91 alloy and nano-SiCp/AZ91 composite were compared at temperature ranges of 523 K-673 K and strain rates of 0.001-1 s-1. Positive impact of SiC nanoparticles on pinning grain boundaries and inhibiting grain growth was not obvious when deformation temperature was below 623 K, but was remarkable when the temperature was above 623 K...

In this work, the influence of intermetallic particle fragmentation during hot rolling as cast structure on evolution textures in aluminum alloys 8011, 5182 and 1565 was investigated. For purpose, laboratory multi-pass material carried out. At various degrees deformation, process stopped, metal quenched sent for optical electron microscopy to investigate large particles. addition, grain studied...

The interactive deformation and visualization of volumetric objects is still a challenging problem for many application areas. We present a novel integrated system which implements physically-based deformation and volume visualization of tetrahedral meshes on modern graphics hardware by exploiting the last features of vertex and fragment shaders. We achieve fast and stable deformation of tetrah...

Deformation behaviour of rolled AZ31 sheets that were subjected to the accumulative roll bonding was investigated. Substantially refined microstructure of samples was achieved after the first and second pass through the rolling mill. Sheets texture was investigated using an X-ray diffractometer. Samples for tensile tests were cut either parallel or perpendicular to the rolling direction. Tensil...

Titanium alloys exhibit mechanical and physical properties that fit structural applications demanding light-weight, corrosion resistance and biocompatibility. Ceramic reinforcements can further improve some of these mechanical properties, such as wear resistance, specific stiffness and specific strength. In comparison to continuous reinforced titanium alloys, the particle reinforced alloys (PRT...

High strength low alloy steels are widely used in gas industry, so shield metal arc welding in pipelines to transport natural gas from Iran is of great importance. For experimental investigation of seam weld and integrity of girth weld, destructive and non-destructive tests are required. In this article the effects of normal heat treatment on properties of multi pass welding in different situat...
