The influence of mould level instability during continuous casting on the unevenness initial solidified shell in hypo-peritectic steels has been investigated. Water model experiments and in-plant revealed that instability, which increases with increasing speed, is related to longitudinal cracking resulting from solidification shell. A numerical considers effect was developed used simulate forma...

This study aims to evaluate the weldability of dissimilar welds with Inconel 625 and Hastelloy C-276 nickel-based alloys deposited on ASTM A36 AISI 1045 carbon steel plates. The were carried out by GMAW process evaluated Trans-Varestraint test. test results statistically evaluated, Fusion Zone solidification processes simulated in JMatPro software using several dilution levels. analysis varianc...

improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

Database cracking has been an area of active research in recent years. The core idea of database cracking is to create indexes adaptively and incrementally as a side-product of query processing. Several works have proposed different cracking techniques for different aspects including updates, tuple-reconstruction, convergence, concurrency-control, and robustness. However, there is a lack of any...
