Thermomechanical Grain Refinement in AA6082-T6 Thin Plates under Bobbin Friction Stir Welding
Metals, 2018 Bobbin friction stir welding (BFSW), with its fully penetrated pin and double-sided shoulder, can provide high rates of heat generation. This produces solid-state thermo-mechanical grain refinement.

EBSD study on magnetic field altering crystal texture and grain growth during laser-hybrid welding
Materials & Design, 2022 In this study, evolutions of austenite and ferrite microstructures and relevant variations of performances were analyzed during laser-arc welding 316L austenitic stainless steel with a magnetic field. For austenite grains, the magnetic field gave rise to

Relationship between casting modulus and grain size in cast A356 aluminium alloys [PDF]
, 2012 Microstructure of Al-Si alloy castings depends most generally on melt preparation and on the cooling rate imposed by the thermal modulus of the component. In the case of Al-Si alloys, emphasis is put during melt preparation on refinement of pro-eutectic (

Molecular Oncology, EarlyView.Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Molecular Oncology, EarlyView.Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Grain refinement of AZ91D alloy by intensive melt shearing and its persistence after remelting and isothermal holding [PDF]
China Foundry, 2013 Intensive melt shearing has a significant grain refining effect on some light alloys. However, the persistence of the grain refining effect during isothermal holding and remelting is still unclear, although it is very important for the practical ...
