1. 1. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel

   University essay from KTH/Materialvetenskap

   Author : Doom Eleanor Ihensekhien; [2022]
   Keywords : Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

   Abstract : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. READ MORE

3. 2. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

   University essay from Jönköping University

   Author : Ruslan Sevastopolev; [2020]
   Keywords : High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

   Abstract : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. READ MORE

4. 3. The Effect of Solidification time and Cooling rate on the Ultimate tensile Strength of Grey Cast Iron.

   University essay from KTH/Materialteknologi

   Author : Dinesh Sundaram; [2018]
   Keywords : Lamellar graphite iron; tensile properties; pearlitic properties; cooling rate; solidification time; Magmasoft.;

   Abstract : Tensile strength modelling is usually done to predict the mechanical properties of lamellargraphite iron considering microstructural features. This work attempts to create a simplifiedmodel incorporating cooling rate and solidification time without considering themicrostructural features. READ MORE

5. 4. Homogenization of Precipitation Hardening Nickel Based Superalloys

   University essay from Materialvetenskap

   Author : Olutayo Adegoke; [2012]
   Keywords : ;

   Abstract : Allvac 718 Plus and Haynes 282 are relatively new precipitation hardening nickel based superalloys with good high temperature mechanical properties. In addition, the weldability of these superalloys enhances easy fabrication. READ MORE

6. 5. Effect of manufacturing conditions and polymer ratio on the permeability and film morphology of ethyl cellulose and hydroxypropyl cellulose free-films produced by using a novel spray method.

   University essay from Institutionen för farmaci

   Author : Annica Jarke; [2009]
   Keywords : free-film; confocal laser scanning microscopy; water permeability;

   Abstract : This thesis considers the effect of manufacturing conditions and polymer ratio on water permeability and morphology of free-films. A novel spray method for producing ethyl cellulose (EC) and hydroxypropyl cellulose (HPC) free-films was developed where several process parameters was controlled. READ MORE
