Based on the latest studies, the defect related to mixed-grain structure with millimeter-grade coarse grains (MCGs) is often created in heavy forgings parts, such as nuclear main pipes fabricated from 316LN steel. Modification of such type forging components can only be run via recrystallization.
recently the deformation heterogeneity of 316LN steel with mixed-grain structures were examined experimentally, which showed that the MCGs were more affected to deform than fine grains even if MCGs are with hard orientations. Therefore, a two-stage technique was investigated to refine MCGs, which causes the advantage of this deformation heterogeneity.
The latest research study involves many of the critical scientific and technological features of laser welding of thermoplastic materials, showing the process basic and how the degree of sophistication for LTW of polymers has advanced over time.
End-of-life tires are a challenging type of waste since they are difficult to shred and are expensive to treat and get rid of. However, tire-derived fuel is an extremely good alternative to the traditional fuels used in cement kilns, like oil, coal, and petroleum coke.
The latest research study provides a deep characterization (including petro physical, mechanical properties and compositional analysis) of class G cement samples retrieved from a wellbore system exposed to downhole conditions for 33 years.
Based on recent studies, formation mechanisms of multistage microstructures are examined and then the techniques of microstructure control are presented. Additively manufactured microstructures are developed during and after solidification of melt pool. A comprehensive processing map is presented for metals additive manufacturing.
