The superplasticity effect during upsetting of low-carbon steels develops in the temperature range Ac 1s-Ac 3s, to a greater extent close to Ac 3s with deformation rates isindotsime(3-7)times10 -3 sec -1, and it is characterized by a simultaneous reduction in deformation resistance, absence...
The present work concerns the effect of the temperature of heating for rolling on the structure and properties of low-carbon (VSt3ps) and low-alloy (09G2S, 09G2FB, 16G2AF, 15G2AFDps, 14Kh2GMR) building steels. In order to bring the structure of the specimens into correspondence with...
Structure and Properties of Iron (Chromium Steel)–High-Carbon Ferrochrome Powder Composites Article 01 January 2020 The Wear Mechanism of High-Boron, Medium-Carbon Alloy at High Temperature Article 14 March 2016 Microstructure evolution and mechanical properties of high-boron steel with different...
Comment on the properties-structure-deformation relationship for carbon steelThe trend towards the greater use of plastic working in the manufacturing industry arises from the necessity of using such production processes as will ensure good utilisation of material, automisation of production, and a ...
In order to design a low-cost high temperature ferrite alloy, the effects of carbon, and titanium on its solidification structure and properties have been studied. When the carbon content is increased from 0.07 to 0.35 wt%, the alloy grains becomes finer, and the grain boundaries become wider...
Wood, one of the oldest building materials, has been continuously reinvented throughout history. As contemporary architecture becomes more and more concerned with sustainability and environmental responsibility, the popularity of the material has also increased. As trees absorb carbon dioxide during their ...

37.Composite retains its own distinctive properties and has properties that can not be achieved by any of the components acting alone . 复合材料既保留了各组分原有的性能,又具有每种组分单独存在时所不具备的性能。 38.Carbon-epoxy composites are two thirds the weight of aluminum ,and two and a ...
In order to understand the effect of the solidification structure on the formability of ultra low carbon ferritic stainless steel (FSS),this work studies the ridging phenomenon and the deep-drawing property in detail and the research method was X-ray diffraction (XRD) and scanning electron microsc...
The residual stress due to welding in steel and alloy structures is analyzed. The greatest residual stress is produced by cooling of the welded structure. The results of calculations are in satisfactory agreement with the experimental deformation of the structure in welding on a test bench. The te...
