چکیده
The paper demonstrates the capability of developed phase transformation model to design cooling conditions in Stelmor process allowing for obtaining different types microstructures wire rod 32CrB4 steel. based on modified JMAK equation was using results tests conducted a DIL 805 A/D/T dilatometer. is composed sub-models ferritic, pearlitic, bainitic and martensitic transformations. Its predictive confirmed industrial by performing trials with settings fans involved line CMC Poland. Excellent performance achieved through modification commonly used equations which allows accurate predictions transformations start finish temperatures, as well volume fraction microstructural constituents, wide range rates. It demonstrated that can effectively be applied process, will result required composition rod.

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
